151: It takes a "remove" option to remove all the staged
152: files.
153:
154: vms_eco_level.h This sets the ECO level for the PCSI kit name.
155:
156:
157: How to Build:
158:
159: The GNV based build and the DCL based build procedures are not compatible
160: and you must make sure that none of the build files are present before
161: running a different type of build. Use the "REALCLEAN" option for
162: BUILD_VMS.COM and the "REALCLEAN" option for clean_gnv_curl.com.
163:
164: The (brute-force) DCL based builder is [.packages.vms]build_vms.com.
165: Comments in this procedure describe various optional parameters which
166: enable or disable optional program features, or which control the build
167: in other ways. Product files (.EXE, .H, .LIS, .MAP, .OBJ, .OLB, ...)
168: should be produced in an architecture-specific subdirectory under this
169: directory ([.ALPHA], [.IA64], [.VAX]).
170:
171: The file curl_gnv_build_steps.txt contains information on buildling using
172: the GNV tool kit, building a shared libcurl, and producting a PCSI kit for
173: distribution. The curl_gnv_build_steps.text is included in the release
174: notes file of the PCSI kit.
175:
176: The building with 64 bit pointers does not currently work.
177:
178: The build procedure will detect if HP OpenSSL, LDAP, and Kerberos are
179: installed and default to building with them.
180:
181: The build procedure will also detect if a compatible ZLIB shared image
182: is installed from a PCSI kit and default to using it.
183:
184: Example build commands:
185:
186: @ [.packages.vms]build_vms.com CLEAN
187: @ [.packages.vms]build_vms.com LARGE LDAP
188: submit /noprint [.packages.vms]build_vms.com /param = (LARGE, LDAP)
189:
190: The build_vms.com procedure does not build the shared image file or the PCSI
191: kit. If you have built a curl with ZLIB and HPSSL support as well as if
192: LDAP and Kerberos installed, you can use the GNV_LINK_CURL.COM file.
193:
194: The GNV_LINK_CURL.COM contains information on how to link and run with a newer
195: version of HP SSL than what may be install on an Alpha or IA64 based system.
196:
197: To build the PCSI kit, follow the instructions in the file
198: curl_gnv_build_steps.txt.
199:
200: Other Notes:
201:
202: This release fixes known bugs #22, and #57 in the [curl.docs]known_bugs.
203: file.
204:
205: The libcurl formdata.c module and Curl tools post form now have some
206: understanding of VMS file types. Files will be posted in STREAM_LF format.
207:
208: The Curl tool now has some understanding of VMS file types and will upload the
209: files in STREAM_LF format.
210:
211: When CURL is uploading a VARIABLE format VMS file, it is less efficient as in
212: order to get the file size, it will first read the entire file once, and then
213: read the file again for the actual upload.
214:
215: The Curl tool will now always download files into STREAM_LF format. Even if a
216: file by that name with a different format already exists. This is needed to
217: allow interrupted downloads to be continued.
218:
219:
220: The libcurl file module still does not understand VMS file types and requires
221: the input files to be in STREAM_LF to work property.
222:
223: The test suites are not supported as of 7.11.0.
224:
225: The curlmsg.sdl and curlmsg.h files are generated from curlmsg.msg.
226: This is not done automatically, since the .MSG file is a hand edit
227: of the relevant stuff from the curl.h file. If you want to do this
228: yourself you'll need the SDL package from the freeware collection.
