On attempting to use this cross-compiler, it reports that it cannot find crti.o. (This was tested in a number of ways, including compiling glibc as that is the next stage in building the cross compiler toolchain.) The source for crti is in the config directory for the MIPS processor but is not being accessed.I can compile this manually and copying the resultant file into the proper place. Using the cross-compiler now, I then get the error that the cross-compiler cannot find crt1.o. There is no sourcecode for crt1 in the MIPS directory. The only other crt file in that directory is for crtn - this file will not compile at all. The main compiler I am using for building the cross-compiler is GCC 3.4.3 and was built using the following options: Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux Thread model: posix gcc version 3.4.3 20050227 (Red Hat 3.4.3-22.1) Copying the .o files from a third-party toolchain, the cross-compiler will progress a good deal further. However, it will fail when cross-compiling either glibc or newlib. In the case of newlib, it crashes at ../gcc/libstdc++-v3/libmath/stubs.c ../../../../gcc/libstdc++-v3/libmath/stubs.c: In function 'floorl': /usr/mips/mipsisa64sb1-unknown-linux-gnu/include/bits/mathinline.h:530: error: impossible register constraint in 'asm' /usr/mips/mipsisa64sb1-unknown-linux-gnu/include/bits/mathinline.h:530: error: impossible register constraint in 'asm' ../../../../gcc/libstdc++-v3/libmath/stubs.c:203: error: unrecognizable insn: (insn 20 19 21 0 /usr/mips/mipsisa64sb1-unknown-linux-gnu/include/bits/mathinline.h:530 (set (reg/v:DF 32 $f0 [orig:195 __value ] [195]) (asm_operands/v:DF ("frndint") ("=t") 0 [ (reg/v:DF 32 $f0 [orig:195 __value ] [195]) ] [ (asm_input:DF ("0")) ] ("/usr/mips/mipsisa64sb1-unknown-linux-gnu/include/bits/mathinline.h") 530)) -1 (insn_list:REG_DEP_TRUE 19 (nil)) (nil)) ../../../../gcc/libstdc++-v3/libmath/stubs.c:203: internal compiler error: in reload_cse_simplify_operands, at postreload.c:393 The cross-compiler was built using the following configuration settings: Target: mipsisa64sb1-unknown-linux-gnu Configured with: ../gcc/configure --target=mipsisa64sb1-unknown-linux-gnu --prefix=/usr/mips --without-headers --with-newlib --with-gnu-as --with-gnu-ld --with-local-prefix=/usr/mips/mipsisa64sb1-unknown-linux-gnu --disable-shared --enable-languages=c Thread model: posix gcc version 4.1.0 20050901 (experimental) I'm running out of ideas for workarounds to build a 64-bit bigendian MIPS toolchain, so any known-to-work workarounds or patches would be much appreciated. -- Summary: Crosscompiler looks for files it never built Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: imipak at yahoo dot com CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: i386-linux-gnu GCC host triplet: i386-linux-gnu GCC target triplet: mipsisa64sb1-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23687
