It also requires the GNV Bash 4.2.45 kit as an update from the 24 same location or from the sourceforge.net GNV project. 25 26 The HP C 7.x compiler was used for building the GNV version. 27 28 The source kits are provided in backup savesets inside of the PCSI install kit. 29 30 Backup save sets are currently the only distribution medium that I can be 31 sure is installed on a target VMS system that will correctly unpack files 32 with extended character sets in them. You may need to adjust the ownership 33 of the restored files, since /Interchange/noconvert was not available at the 34 time that this document was written. 35 36 [gnv.common_src]curl_*_original_src.bck is the original source of the curl kit 37 as provided by the curl project. [gnv.vms_src]curl-*_vms_src.bck, if present, 38 has the OpenVMS specific files that are used for building that are not yet in 39 the curl source kits for that release distributed https://curl.haxx.se 40 41 These backup savesets should be restored to different directory trees on 42 an ODS-5 volume(s) which are referenced by concealed rooted logical names. 43 44 SRC_ROOT: is for the source files common to all platforms. 45 VMS_ROOT: is for the source files that are specific to OpenVMS. 46 Note, you should create the VMS_ROOT: directory tree even if it is 47 initially empty. This is where you should put edits if you are 48 making changes. 49 LCL_ROOT: is manually created to have the same base and sub-directories as 50 SRC_ROOT: and VMS_ROOT: 51 52 The logical name REF_ROOT: may be defined to be a search list for 53 VMS_ROOT:,SRC_ROOT: 54 55 The logical name PRJ_ROOT: is defined to be a search list for 56 LCL_ROOT:,VMS_ROOT:,SRC_ROOT: 57 58 For the make install process to work, it must have write access to the 59 directories referenced by the GNU: logical name. 60 61 In future releases of GNV, and with GNV Bash 4.3.30 installed, this name 62 should be GNV$GNU: 63 64 As directly updating those directories would probably be disruptive to other 65 users of the system and require elevated privilege, this can be handled by 66 creating a separate directory tree to install into which can be referenced 67 by the concealed rooted logical name new_gnu:. A concealed logical name of 68 OLD_GNU: can be set up to reference the real GNV directory tree. 69 70 Then a local copy of the GNU/GNV$GNU logical names can be set up as a search 71 list such as NEW_GNU:,OLD_GNU: 72 73 The directory NEW_GNU:[usr] should be created. The make install phase should 74 create all the other directories. 75 76 The make install process may abort if curl is already because it can not 77 uninstall the older version of curl because it does not have permission. 78 79 The file stage_curl_install.com is used set up a new_gnu: directory tree 80 for testing. The PCSI kitting procedure uses these files as input. 81 82 These files do not create the directories in the VMS_ROOT and LCL_ROOT 83 directory trees. You can create them with commands similar to: 84 85 $ create/dir lcl_root:[curl]/prot=w:re 86 $ copy src_root:[curl...]*.dir - 87 lcl_root:[curl...]/prot=(o:rwed,w:re) 88 $ create/dir vms_root:[curl]/prot=w:re 89 $ copy src_root:[curl...]*.dir - 90 vms_root:[curl...]/prot=(o:rwed,w:re) 91 92 One of the ways with to protect the source from being modified is to have 93 the directories under src_root: owned by a user or resource where the build 94 username only has read access to it. 95 96 97 Note to builders: 98 99 GNV currently has a bug where configure scripts take a long time to run. 100 Some of the configure steps take a while to complete, and on a 600 Mhz 101 DS10 with IDE disks, taking an hour to run the CURL configure is normal. 102 103 The following messages can be ignored and may get fixed in a future version 104 of GNV. The GNV$*.OPT files are used to find the libraries as many have 105 different names on VMS than on Unix. The Bash environment variable 106 GNV_CC_QUALIFIERS can override all other settings for the C Compiler. 107 108 ? cc: No support for switch -warnprotos 109 ? cc: Unrecognized file toomanyargs 110 ? cc: Warning: library "ssl" not found 111 ? cc: Warning: library "crypto" not found 112 ? cc: Warning: library "gssapi" not found 113 ? cc: Warning: library "z" not found 114 u unimplemented switch - ignored 115 116 117 With these search lists set up and the properly, curl can be built by 118 setting your default to PRJ_ROOT:[curl.packages.vms] and then issuing 119 either the command: 120 121 $ @pcsi_product_gnv_curl.com 122 123 or 124 125 $ @build_gnv_curl.com. 126 127 The GNV configure procedure takes considerably longer than the DCL build 128 procecure takes. It is of use for testing the GNV build environment, and 129 may not have been kept up to date. 130 131 The pcsi_product_gnv_curl.com needs the following logical names which 132 are described in the section below: 133 134 gnv_pcsi_producer 135 gnv_pcsi_producer_full_name 136 stage_root 137 vms_root1 (Optional if vms_root is on a NFS volume) 138 src_root1 (Optional if src_root is on a NFS volume) 139 140 The pcsi_product_gnv_curl.com is described in more detail below. It does 141 the following steps. The build steps are only done if they are needed to 142 allow using either DCL or GNV based building procedures. 143 144 $ @build_vms list 145 146 $ @gnv_link_curl.com 147 148 $ @build_gnv_curl_release_notes.com 149 150 $ @backup_gnv_curl_src.com 151 152 $ @build_gnv_curl_pcsi_desc.com 153 154 $ @build_gnv_curl_pcsi_text.com 155 156 $ @stage_curl_install remove 157 $ @stage_curl_install 158 159 Then builds the kit. 160 161 The build_gnv_curl.com command procedure does the following: 162 163 $ @setup_gnv_curl_build.com 164 165 $ bash gnv_curl_configure.sh 166 167 $ @clean_gnv_curl.com 168 169 $ bash make_gnv_curl_install.sh 170 171 $ @gnv_link_curl.com 172 173 $ @stage_curl_install.com 174 175 $ purge new_gnu:[*...]/log 176 177 To clean up after a GNV based build to start over, the following commands are 178 used: 179 180 $ bash 181 bash$ cd ../.. 182 bash$ make clean 183 bash$ exit 184 185 Then run the @clean_gnv_curl.com. Use the parameter "realclean" if you are 186 going to run the setup_gnv_curl_build.com and configure script again. 187 188 $ @clean_gnv_curl.com realclean 189 190 If new public symbols have been added, adjust the file gnv_libcurl_symbols.opt 191 to have the new symbols. If the symbols are longer than 32 characters, 192 then they will need to have the original be exact case CRC shortened and 193 an alias in upper case with CRC shortened, in addition to having an exact 194 case truncated alias and an uppercase truncated alias. 195 196 The *.EXE files are not moved to the new_gnu: directory. 197 198 After you are satisfied with the results of your build, you can move the 199 files from new_gnu: to old_gnu: at your convenience. 200 201 Building a PCSI kit for an archictecture takes the following steps after 202 making sure that you have a working build environment. 203 204 Note that it requires manually creating two logical names as described 205 below. It is intentional that they be manually set. This is for 206 branding the PCSI kit based on who is making the kit. 207 208 1. Make sure that you have a staging directory that can be referenced 209 by the path STAGE_ROOT:[KIT] 210 211 2. Edit the file curl_release_note_start.txt or other text files to 212 reflect any changes. 213 214 3. Define the logical name GNV_PCSI_PRODUCER to indicate who is making 215 the distribution. For making updates to an existing open source 216 kit you may need to keep the producer the same. 217 218 4. Define the logical name GNV_PCSI_PRODUCER_FULL_NAME to be your full 219 name or full name of your company. 220 221 5. If you are producing an update kit, then update the file 222 vms_eco_level.h by changing the value for the VMS_ECO_LEVEL macro. 223 This file is currently only used in building the PCSI kit. 224 225 6. Edit the file PCSI_GNV_CURL_FILE_LIST.TXT if there are new files added 226 to the kit. These files should all be ODS-2 legal filenames and 227 directories. 228 229 A limitation of the PCSI kitting procedure is that when selecting files, 230 it tends to ignore the directory structure and assumes that all files 231 with the same name are the same file, so every file placed in the kit 232 must have a unique name. Then a procedure needs to be added to the kit 233 to create an alias link on install and remove the link on remove. 234 235 Since at this time curl does not need this alias procedure, the steps 236 to automatically build it are not included here. 237 238 While newer versions of PCSI can support ODS-5 filenames, not all versions 239 of PCSI on systems that have ODS-5 filenames do. So as a post install 240 step, the PCSI kit built by these steps does a rename to the correct 241 case as a post install step. 242 243 7. Edit the build_curl_pcsi_desc.com and build_curl_pcsi_text.com if you 244 have changed the version of ZLIB that curl is built against. 245 246 8. Prepare to backup the files for building the kit. 247 248 Note that if src_root: or vms_root: are NFS mounted disks, the 249 step of backing up the source files will probably hang or fail. 250 251 You need to copy the source files to VMS mounted disks and create 252 logical names SRC_ROOT1 and VMS_ROOT1 to work around this to to 253 reference local disks. Make sure src_root1:[000000] and 254 vms_root1:[000000] exist and can be written to. 255 256 The command procedure compare_curl_source can be used to check 257 those directories and keep them up to date. 258 259 @compare_curl_source.com SRCBCK UPDATE 260 261 This compares the reference project source with the backup 262 staging directory for it and updates with any changes. 263 264 @compare_curl_source.com VMSBCK UPDATE 265 266 This compares the VMS specific source with the backup 267 staging directory for it and updates with any changes. 268 269 Leave off "UPDATE" to just check without doing any changes. 270 271 If you are not using NFS mounted disks and do not want to have a 272 separate directory for staging the sources for backup make sure 273 that src_root1: and vms_root1: do not exist. 274 275 9. Build the PCSI kit with @pcsi_product_gnv_curl.com 276 277 The following message is normal: 278 %PCSI-I-CANNOTVAL, cannot validate 279 EAGLE$DQA0:[stage_root.][kit]VMSPORTS-AXPVMS-CURL-V0731-0-1.PCSI;1 280 -PCSI-I-NOTSIGNED, product kit is not signed and therefore has 281 no manifest file 282 283 This will result in an uncompressed kit for the target platform. 284 On Alpha and Integrity, the pcsi_product_gnv_curl.com can be used with 285 the "COMPRESSED" parameter to build both a compressed and uncompressed 286 kits. 287 288 Good Luck. 289
