--- Comment #27 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-01-28 09:45:58 UTC --- (In reply to comment #26) > Question : I tried to build my own version, but i did not succeed. > (1) gcc-4.5.2 : ok > (2) gcc-4.5.2 + modified/added files from trunk (4.6) : compilation error on > file match.c > Is it normal that test (2) did not work ? Well, it is not surprising that just applying 4.6 patches do not work on 4.5. After all, one year of development is a lot. During that year the following, user-visible changes were done for Fortran: http://gcc.gnu.org/gcc-4.6/changes.html#fortran Thus, the chance that a patch applies without any changes to an older version is relatively low. > Do i need to modify directly files related to this bug report ? Well, if applying the patch does not work and if you want to use 4.5, you seemingly have to. I assume that the changes to match.c are not difficult, but I have not tried it - and I do not plan to do so. > (3) gcc-4.6 (from trunk) : some errors... (I don't remerber) Without error message, it is difficult to help (and this bug report is the wrong forum*). However, you could also try to use the nightly builds, which are available at http://gcc.gnu.org/wiki/GFortranBinaries * Mailing list, cf. http://gcc.gnu.org/lists.html try gcc-help@ or fortran@ but first glance at the instructions at http://gcc.gnu.org/install/
