Created attachment 449218 [details] The configure test that is failing Trying to install games-engines/love-0.7.2-r1, I got: checking for library containing lua_pcall... -llua checking for library containing ilInit... no configure: error: Can't LÖVE without DevIL The configure log at /host/var/tmp/portage/games-engines/love-0.7.2-r1/work/love-HEAD/config.log showed the reason: Reason ====== configure:15361: i686-pc-linux-gnu-gcc -o conftest -O2 -march=pentium4 -pipe -Wl,-O1 -Wl,--as-needed conftest.c -lIL -llua -lopenal -lGL -lSDL -lm >&5 /usr/lib/libIlmThread-2_1.so.11: undefined reference to `pthread_create' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_wait' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_init' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_destroy' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_getvalue' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_post' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_trywait' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `pthread_join' collect2: error: ld returned 1 exit status Attempt to resolve ============= Re-merging media-libs/ilmbase-2.1.0 (which is the owner of /usr/lib/libIlmThread-2_1.so.11) did NOT resolve the issue. Trying the configure test as a separate program, say, love.c (see attachment), showed why: i686-pc-linux-gnu-gcc -o love -O2 -march=pentium4 -pipe -Wl,-O1 -Wl,--as-needed love.c -lIL -llua -lopenal -lGL -lSDL -lm /usr/lib/libIlmThread-2_1.so.11: undefined reference to `pthread_create' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_wait' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_init' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_destroy' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_getvalue' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_post' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `sem_trywait' /usr/lib/libIlmThread-2_1.so.11: undefined reference to `pthread_join' collect2: error: ld returned 1 exit status Adding -pthread to the invocation resolves the problem: i686-pc-linux-gnu-gcc -pthread -o love -O2 -march=pentium4 -pipe -Wl,-O1 -Wl,--as-needed love.c -lIL -llua -lopenal -lGL -lSDL -lm (no errors, love executable created). Solution ======= The configure script should use '-pthread' as above for its devil test, before it spits "Can't LÖVE without DevIL".
Confirming. This bug also affects love-0.8.0, not sure how to proceed.
I cannot reproduce with 0.7.2-r2 or 0.8.0-r1 Please retry
Suddenly hitten by this one also, due to recent lua.*eclasses The really weird thing is that only one of my box is affected, the two other gentoo boxes, upgraded without any troubles. The three boxes have slightly different use flag, but mainly share the same base.
nvtt flag is culprit on my box so may be love:0.7 and love:0.8 should depend on media-libs/devil[-nvtt] I'll may dig further, to expose a real fix, rather than a workaround
