Bug 519836 – sys-apps/sandbox-2.6-r1 - wrappers.c:(.text.get_dlsym+0x44): undefined reference to `dlvsym'

• Product: Portage Development
• Status: RESOLVED NEEDINFO

[Description Jacob Martin 2014-08-13 16:23:42 UTC]

Whenever I try to emerge sandbox-2.6-r1, it errors out with undefined references to functions contained in libdl.

.

.

*** Warning: Linking the shared library libsandbox.la against the
*** static library ../libsbutil/.libs/libsbutil.a is not portable!
.libs/libsandbox_la-wrappers.o: In function `get_dlsym':

I do have libdl on my system, and the configure step of the emerge shows that some of these functions are indeed found:

.
.
.
checking for library containing dlopen... checking for stackoverflow_install_handler in -lsigsegv... (cached) false
checking for __sync_lock_test_and_set... none required
checking for dlvsym... yes
checking for va_copy... va_copy
checking for library containing dlopen... yes
checking truncate argument type... off_t
checking for RTLD_NEXT... none required
checking for dlvsym... yes
.
.
.


I have tried recompiling glibc (currently have [2.17:2.2]), but that didn't work.

Is this a bug or have I somehow messed up something?  This is a very old gentoo system which I have been upgrading over many years, so perhaps there was some problem.

Reproducible: Always

Steps to Reproduce:
emerge sandbox
Actual Results:  
didn't compile

Expected Results:  
compile

1) Please post your `emerge --info' output in a comment.
2) Please attach the entire build log to this bug report.

Sorry, rookie mistake.  The build logs for sandbox are attached for after emerging the newest version of glibc:

sys-libs/glibc-2.19-r1:2.2

[Comment 5 SpanKY 2014-08-20 15:37:35 UTC]

your compiler settings are terrible and plain broken (-l flags should never be in there).  please reset to sane values (like -O2 -pipe) and retry building.

[Comment 6 Jacob Martin 2014-09-04 13:21:37 UTC]

Thanks for sharing your expertise, with -O2 -pipe, it works like a charm!

Apparently one of the flags messes things up quite a bit, but I'm not sure which one.  Feel free to close the bug. 

Thank you again!
