After an unsuccessful attempt at asking this on -questions... I believe that I could work my way through the problem below if I could build a vanilla gcc 2.7.2.3 on FreeBSD 3.3-R. Attempting to build a fresh 2.7.2.3, 1. configure 2. remove references to gnumalloc in Makefile and cp/Makefile 3. make LANGUAGES=c and I get --- snip --- ./xgcc -B./ -DIN_GCC -g -I./include enquire.o -o enquire /usr/libexec/elf/ld: cannot open crt0.o: No such file or directory *** Error code 1 Stop. --- snip --- I presume that this is an a.out vs elf issue -- gcc is trying to build an a.out version and 3.3-R is elf. However, I get the same problem if I try configure with "configure i386-elf-freebsd". Suggestions? Charles P.S. I know that 3.3-R uses gcc 2.7.2.3 internally. However, I would like to build a separate binary for StackGuard. -----Original Message----- From: Charles Randall [mailto:crandall@matchlogic.com] Sent: Tuesday, November 02, 1999 9:37 AM To: freebsd-questions@freebsd.org Subject: Immunix Stackguard for FreeBSD? Has anyone successfully built Immunix stackguard on FreeBSD? Here's a link to the original research project, http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/ The latest development seems to be reflected here, http://www.wirex.com/ and http://immunix.org/ On the downloads page at immunix.org, there's an RPM of patches to gcc 2.7.2.3. I've un-packed that on my 3.3-R system, applied all of the patches, run 'configure', and 'make LANGUAGES=c'. First, the build fails trying to find gnumalloc. After removing that dependency in Makefile and cp/Makefile (assuming that BSD malloc will be used), the build eventually dies with: --- snip --- ./xgcc -B./ -DIN_GCC -O -I./include enquire.o -o enquire /usr/libexec/elf/ld: cannot open crt0.o: No such file or directory *** Error code 1 Stop. --- snip --- I presume that this is because 3.3-R uses elf and gcc is trying to build an a.out version. Thinking about that a bit, I ran 'make distclean', 'configure i386-elf-freebsd', and 'make LANGUAGES=c' in an attempt to build an elf-specific version. After removing the dependencies on gnumalloc again, the build died in the same place, --- snip --- ./xgcc -B./ -DIN_GCC -O -I./include enquire.o -o enquire /usr/libexec/elf/ld: cannot open crt0.o: No such file or directory *** Error code 1 Stop. --- snip --- Am I missing a compatibility library or something?
