Bug 326549 – net-misc/curl-7.21.0 doesn't build if I have media-video/rtmpdump-2.2e-r3 installed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Zeev Tarantov 2010-07-02 05:43:31 UTC]

configure for libcurl finds librtmp/rtmp.h installed by media-video/rtmpdump and decides to use that, but it doesn't link libcurl.so to the library, so libcurl.so has undefined symbols RTMP_*. Building curl fails at linking the executable.

I blame curl's configure script: it found out that it can't link with -lrtmp, why set USE_LIBRTMP to 1?

I'm using --as-needed so maybe symptoms would be different otherwise.

I'm attaching config.log and build.log


Reproducible: Always

Steps to Reproduce:
1. emerge -1 =media-video/rtmpdump-2.2e-r3
2. emerge -1 =net-misc/curl-7.21.0
3.

Actual Results:

Expected Results:  
Expected to either disregard that library if it can't link against it (it's not build with -fPIC), or link against it properly (media-video/rtmpdump only builds a static lib, though, so that needs to change).


Workaround: emerge -aC media-video/rtmpdump && emerge net-misc/curl && emerge -1 media-video/rtmpdump

Note: media-video/rtmpdump is pulled in by ffmpeg[rtmp]

Even if it works, it is still an automagic dependency. I get the same error though.

[Comment 4 Adrian Bassett 2010-07-04 11:30:01 UTC]

Worth noting that rtmpdump 2.3 has been released.  This includes a shared lib:

$ ls /usr/lib/librtmp*
-rw-r--r-- 1 root root 152888 Jul  2 14:20 /usr/lib/librtmp.a
lrwxrwxrwx 1 root root     12 Jul  2 14:20 /usr/lib/librtmp.so -> librtmp.so.0
-rwxr-xr-x 1 root root 104056 Jul  2 14:20 /usr/lib/librtmp.so.0

and curl 7.21.0 builds OK against this version (automagic dependency or not).

A simple rename of media-video/rtmpdump-2.2e-r3.ebuild to media-video/rtmpdump-2.3.ebuild is enough (apart from a change to SRC_URI to fetch a .tgz rather than a tar.gz source bundle.

In case it's of interest I'll attach my 2.3 ebuild (which, when copied to rtmpdump-9999.ebuild, can also be used as a means of building against the SVN trunk) - if anybody can improve the kludge at lines 65-66 that would be useful.

[Comment 6 Markos Chandras (RETIRED) 2010-07-07 22:23:36 UTC]

rtmpdump is on tree now. However this bug will remain open until this automagic dependency gets fixed

Thanks for your ebuild

[Comment 7 Daniel Black (RETIRED) 2010-07-18 09:34:17 UTC]

fix autodependency. May add proper use flag later. Thanks for the bug report Zeev.
