Sorry for the spam, but 'filter-flags "-fPIC"' doesn't work - the Makefile sets it as well. Manual removal (sed in unpack) still doesn't fix the issue; same failure as before. cc -Wall -m32 -march=i486 -Os -fomit-frame-pointer -fno-builtin -ffreestanding -fno-stack-protector -m32 -c -o lib.o lib.c test.c: In function `movinvr': test.c:302: error: can't find a register in class `BREG' while reloading `asm' test.c:364: error: can't find a register in class `BREG' while reloading `asm' I'm out of ideas now - this might have to go upstream.
Just try. -fno-pie -nopie.
Neither of the following substitutions worked (sed shorthand): s/-fPIC/-nopie -no-pie/ s/-fPIC/-fPIC -nopie -no-pie/ They still failed at the same point. Setting GCC profile to -hardenednopiessp succeeds in compiling (no substitutions).
If it's still failing when using -fno-pie -nopie then clearly the cflags are not being propogated down into the source code where it needs to be.
For the permanent record, I'm adding these CFLAGS by hand and running 'make' by hand as well, after running an 'ebuild <ebuild> unpack' [bob@dev-01 memtest86+-2.00] make clean rm -f *.o memtest.bin memtest memtest_shared memtest_shared.bin [bob@dev-01 memtest86+-2.00] grep CFLAGS= Makefile CFLAGS=-Wall -m32 -march=i486 -Os -fomit-frame-pointer -fno-builtin -ffreestanding -fno-pie -nopie -fno-stack-protector [bob@dev-01 memtest86+-2.00] make as -32 -o head.o head.s cc -c -Wall -m32 -march=i486 -Os -fomit-frame-pointer -fno-builtin -ffreestanding -fno-pie -nopie -fno-stack-protector -fno-strict-aliasing -fno-stack-protector reloc.c reloc.c: In function `_dl_start': reloc.c:49: warning: 'got' might be used uninitialized in this function reloc.c:49: warning: 'got' might be used uninitialized in this function cc -Wall -m32 -march=i486 -Os -fomit-frame-pointer -fno-builtin -ffreestanding -fno-pie -nopie -fno-stack-protector -m32 -c -o main.o main.c cc -c -Wall -march=i486 -m32 -Os -fomit-frame-pointer -fno-builtin -ffreestanding test.c test.c: In function `movinvr': test.c:302: error: can't find a register in class `BREG' while reloading `asm' test.c:364: error: can't find a register in class `BREG' while reloading `asm' make: *** [test.o] Error 1
The problem should be fixed in CVS now. Thanks everyone.
