317692 - loading libfreebl3.so fails with NSS 3_11_RC1

Status: RESOLVED INVALID

(NSS :: Libraries, defect, P1)

Description

[Kai Engert [:KaiE:]]

I compiled MOZILLA_1_8_0_BRANCH with NSPR_4_6_1_RC1 and NSS_3_11_RC1.

It fails during NSS_InitReadWrite, I traced it down the the point where NSS tries to load libfreebl3.so.

See the following gdb debug sessions, I marked the interesting places with ##############

Comment 1

[Wan-Teh Chang]

Kai,

Your debugging should focus on why the PR_LoadLibraryWithFlags
call at loader.c:258 fails.  In order for that call to succeed,
libfreebl3.so needs to be in a directory on your LD_LIBRARY_PATH.

You need to modify mozilla/security/manager/Makefile.in to
install libfreebl3.so in $(DIST)/bin, which is added to
LD_LIBRARY_PATH (as ${MOZ_DIST_BIN}) in run-mozilla.sh.  See
http://lxr.mozilla.org/seamonkey/source/build/unix/run-mozilla.sh#335

Comment 2

[Wan-Teh Chang]

One quick experiment is to manually copy libfreebl3.so
to $(DIST)/bin, right next to libsoftokn3.so.  Does that
fix the problem?

Indeed it fixes the problem, thanks.
