I built gcc 3.0.3 about 10 years ago on Solaris 2.7 and would like to build a newer gcc on a system that has been upgraded to Solaris 2.10. My most recent attempt was for gcc 4.0.0 configured with fortran disabled (thus obviating gmp, mpfr and mpc). The build succeeded up until the attempt to link a bunch of object files and a few library files in the directory `gcc' into the file `cc1'. At this point, it complained about undefined symbols and exited with `ld: fatal: Symbol referencing errors. No output written to cc1' with more details in the attachment. I'm guessing I need to build something in order to build the more recent gcc, the candidates will follow. Some notes on the build process: The only accessible compiler is the old gcc I built a decade ago as the license for the vendor compiler expired. Some of the headers changed with Solaris 2.10. One consequential change is that the signal.h file (and the files it includes) will break with the compiler built under the earlier OS version. I was able to get the relevant include files from an unupdated machine and adding an appropriate `-I...' into the Makefiles to find the old version rather than the current vendor version. However, I could not find what option to supply with configure so that the flag would be included automatically. I have built and installed gmake but am currently using vendor binutils. Would I be better off getting the gnu binutils or building an intermediate gcc as an intermediate to the recent version? Would I need something else? Also, once I get that set, what option would go with configure to add the include directory. Thanks for any help. Scott
