curl: destroot merge failure of curl-config with +universal variant because of --host and host_alias

[ToePeu@…]

it raise error because ppc and intel has different curl-config file

its difference is occured by --configure options:

       echo " '--prefix=/opt/local' '--enable-ipv6' '--without-gnutls' '--without-gssapi' '--without-libssh2' '--without-spnego' '--disable-ares' '--disable-ldap' '--disable-ldaps' '--with-libidn' '--with-zlib=/opt/local' '--disable-dependency-tracking' '--with-ssl' '--with-ca-bundle=/opt/local/share/curl/curl-ca-bundle.crt' 'CC=/usr/bin/gcc-4.2' 'CFLAGS=-O2 ' 'LDFLAGS=-L/opt/local/lib ' 'CPPFLAGS=-I/opt/local/include'"

is for intel, but for ppc, it has more ppc-related options

it raise merge failure in destroot path

since i removed difference of both curl-config as fake, problem resolved.

i think there should not be check curl-config here.

ps. when i failed to destroot, and tried -d to make report, destroot failed for everything because it could not recover its state before destroot. it was terrible and i should remove some output of destroot manually.

Presumably I should simply remove '--host=.*' and 'host_alias=.*' from curl-config if present.

Error building universal

[erik.welander@…]

Hi, i have tried to build the package for quite some time now using a PowerBook G4, but the build always fails at the destroot stage. I have completely purged macports and all of its ports, and tried install variants such as installing zlib beforehand.

I have set +universal in variants.conf and tried to install with "sudo port install zlib" followed by "sudo port install curl +ssl" Yet i can never get past the destroot stage. Following the other threads of people having the same problem, i am lead here with a status of the bug being "fixed", yet i can't get past the part

--->  Staging curl into destroot
Error: org.macports.destroot for port curl returned: curl-config differs in /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_net_curl/curl/work/destroot-powerpc//opt/local/bin and /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_net_curl/curl/work/destroot-intel//opt/local/bin and cannot be merged

Any help in the matter would be appreciated. Maybe this bug should be reopened?

Is there a particular reason why you need to build universal? The only reason you would need this is if you need to build software on your PowerBook that can also be run on an Intel Mac.

Please attach the two copies of the curl-config file so that I can see how they differ.

The application will be used within a volunteer organization hosting various activities(programming, karaoke, movie nights). The users/members of this organization gets internet access as well as access to network resources by logging in. I love this Powerbook(1.66Ghz 15") so i'm not very keen on upgrading just yet as it's still a wonderful computer to work with, but i do want other people get access to the programs i make.

I copied "curl-config" from both folders and named them according to architecture.

There are differences between the two files, but they're irrelevant differences: just a few repeated flags. Off the top of my head I don't know why that would be happening.

Maybe Macports halts as soon as it finds any kind of difference at all? Why does not both versions just share the same file? Any way i can test this theory? Simply copying the intel one to the PPC one did not work since it does not like the fact that the directories already exists.

Yes, any difference in a text file will halt the merge; this is intentional because there are not expected to be any differences between the files. MacPorts cannot magically know which one of the two is correct. The question is why the curl build system has produced two different files.

[erik.welander@…]

A quick and dirty fix but it works like a charm and universal builds works with it.

I made i quick and dirty fix to it and it works like it should now, something similar should be done but maybe a bit more clean?

Much to my suprise bash syntax and commands does not work and i do not have any experience or knowledge about TCL.

Upon examining the configure files in the ppc build directory, the flags do needlessly repeat themselves.

[ryandesign (Ryan Carsten Schmidt)]

I'm not comfortable simply ignoring the problem by just picking one of the files and ignoring the other; this will prevent us from learning about any future differences as well, and although the current difference is insignificant, differences future versions of curl might produce might not be. I want to figure out why the curl build system is generating two different files here, and make it stop doing that. Or it might not be the fault of the curl build system; it might be something in the muniversal portgroup causing this, in which case we need to fix that.

This ticket was originally about the failure to merge because of the --host and host_alias parameters. That was fixed in r75686 by removing the --host and host_alias parameters prior to merging, so this ticket should remain closed.

The new problem is about a failure to merge because of repeated SSL flags. Let's handle that issue in #32287.
