Maybe, something changed in gc.h recently? I get .... gcc -O2 -march=pentium-m -pipe -Wall -Wshadow -Wcast-qual -Wno-parentheses -Wno-sign-compare -Werror-implicit-function-declaration -Wno-strict-aliasing -O3 -Wno-unused-label -I../../include -I./../../include -I. -I. -I../util -I../e -I./../regex -I/usr/include/gc -I/var/tmp/portage/sci-mathematics/Macaulay2-0.9.95-r2/work/include -DNDEBUG -c -o M2lib.o M2lib.c M2lib.c: In function 'Macaulay2_main': M2lib.c:436: error: conflicting types for 'GC_get_stack_base' /usr/include/gc/gc.h:886: error: previous declaration of 'GC_get_stack_base' was here M2lib.c:436: warning: declaration of 'GC_get_stack_base' shadows a global declaration /usr/include/gc/gc.h:886: warning: shadowed declaration is here M2lib.c:542: warning: assignment from incompatible pointer type make[2]: *** [M2lib.o] Error 1 Reproducible: Always
Thanks much for the note Andrey! Presently it seems Macaulay doesn't even build for me due to a segmentation fault. This package really frustrates me; I've spend a considerable amount of time in the past to get it to compile and pass all the tests, but everytime one either upgrades library foo or compiler bar it breaks again. Just for completeness, could you please post your emerge --info as well as your version of boehm-gc. Thanks, Markus

I apologize that nothing has happened here in a while, but unfortunately Macaulay2 currently fails to compile both on my x86 and amd64 dev boxes and I have yet to figure out why. best, Markus
Hi Andrey, I've just committed Macaulay2-1.0 to the tree. It compiles fine for me on x86 and amd64. Could you please give it a try and see if it works for you? Please note that dev-libs/boehm-gc-7.* has to be built with USE="-threads" since its thread implementation seems to be broken atm. Thanks, Markus
Since Macaulay2-1.0 is now in the tree please try this one an file a new bug should there be any problems. Thanks, Markus
