If you wish to build the GNU C++ -compiler as well as the GCC compiler, you must first edit -@file{make-gcc.com} and follow the instructions that appear in the -comments. - -@item -In order to use GCC, you need a library of functions which GCC compiled code -will call to perform certain tasks, and these functions are defined in the -file @file{libgcc2.c}. To compile this you should use the command procedure -@file{make-l2.com}, which will generate the library @file{libgcc2.olb}. -@file{libgcc2.olb} should be built using the compiler built from -the same distribution that @file{libgcc2.c} came from, and -@file{make-gcc.com} will automatically do all of this for you. - -To install the library, use the following commands: - -@smallexample -$ library gnu_cc:[000000]gcclib/delete=(new,eprintf) -$ library gnu_cc:[000000]gcclib/delete=L_* -$ library libgcc2/extract=*/output=libgcc2.obj -$ library gnu_cc:[000000]gcclib libgcc2.obj -@end smallexample - -The first command simply removes old modules that will be replaced with -modules from @file{libgcc2} under different module names.

An example would be the when -the source files are on a read-only disk.

Once you have done -this, you can proceed building GCC as described above. (Keep in mind -that @file{gcc_build} is a rooted logical name, and thus the device -names in each element of the search list must be an actual physical -device name rather than another rooted logical name). - -@item -@strong{If you are building GCC with a previous version of GCC, -you also should check to see that you have the newest version of the -assembler}. In particular, GCC version 2 treats global constant -variables slightly differently from GCC version 1, and GAS version -1.38.1 does not have the patches required to work with GCC version 2. -If you use GAS 1.38.1, then @code{extern const} variables will not have -the read-only bit set, and the linker will generate warning messages -about mismatched psect attributes for these variables. These warning -messages are merely a nuisance, and can safely be ignored. - -@item -If you want to build GCC with the VAX C compiler, you will need to -make minor changes in @file{make-cccp.com} and @file{make-cc1.com} -to choose alternate definitions of @code{CC}, @code{CFLAGS}, and -@code{LIBS}. See comments in those files. However, you must -also have a working version of the GNU assembler (GNU as, aka GAS) as -it is used as the back end for GCC to produce binary object modules -and is not included in the GCC sources. GAS is also needed to -compile @file{libgcc2} in order to build @file{gcclib} (see above); -@file{make-l2.com} expects to be able to find it operational in -@file{gnu_cc:[000000]gnu-as.exe}. - -To use GCC on VMS, you need the VMS driver programs -@file{gcc.exe}, @file{gcc.com}, and @file{gcc.cld}. They are -distributed with the VMS binaries (@file{gcc-vms}) rather than the -GCC sources. GAS is also included in @file{gcc-vms}, as is Bison. - -Once you have successfully built GCC with VAX C, you should use the -resulting compiler to rebuild itself. Before doing this, be sure to -restore the @code{CC}, @code{CFLAGS}, and @code{LIBS} definitions in -@file{make-cccp.com} and @file{make-cc1.com}. The second generation -compiler will be able to take advantage of many optimizations that must -be suppressed when building with other compilers. -@end enumerate - -Under previous versions of GCC, the generated code would occasionally -give strange results when linked with the sharable @file{VAXCRTL} library. -Now this should work. - -Even with this version, however, GCC itself should not be linked with -the sharable @file{VAXCRTL}. The version of @code{qsort} in -@file{VAXCRTL} has a bug (known to be present in VMS versions V4.6 -through V5.5) which causes the compiler to fail. - -The executables are generated by @file{make-cc1.com} and -@file{make-cccp.com} use the object library version of @file{VAXCRTL} in -order to make use of the @code{qsort} routine in @file{gcclib.olb}. If -you wish to link the compiler executables with the shareable image -version of @file{VAXCRTL}, you should edit the file @file{tm.h} (created -by @file{vmsconfig.com}) to define the macro @code{QSORT_WORKAROUND}. - -@code{QSORT_WORKAROUND} is always defined when GCC is compiled with -VAX C, to avoid a problem in case @file{gcclib.olb} is not yet -available. |
