Bugzilla Bug 189040

When compiling mbuffer-20070317 with USE="ssl" the ebuild fails, because
configure sets the wrong library for md5 support.It gets -lmd5 which should be
-lssl (a manual configure picks the right library). As result of this the
ebuild later complains about a missing md5.h and crashes.

Reproducible: Always

Steps to Reproduce:
1. emerge =mbuffer-20070317 USE="ssl"

Actual Results:  
*bang* md5.h not found

you need to post real info ... saying "it fails" is not debuggable

start with the actual emerge output and the config.log in the build dir

Relevant part of emerge.log:

Found under cache variables in config.log:

Hope this is verbose enough.

dont post snippets of config.log, post the whole thing as an attachment

the md5 functions should have been found in libssl (MD5_Init)

Created an attachment (id=128333) [details]
The resulting config.log with the wrong value.

your -Wl,--as-needed is screwing things up

i noticed you *still* havent posted `emerge --info`

Created an attachment (id=128366) [details]
emerge --info

You are right, if I temporarily change the LDFLAGS to "" it compiles just fine.
So I guess the best way would be to strip the flags in the ebuild?

no, the configure script should be tweaked ... it asks for -lssl when in
reality it wants -lcrypto

mbuffer-20070518 should work

I have no clue why it doesn't work but I had to strip the LDFLAGS to make it
work.
