Is it possible that you had an older version of GCC installed on this machine, and that you didn't remove that old installation before installing the new one? If so, you want to remove everything and reinstall, since it's quite possible that your problems all stem from mixing two different versions of GCC. > and un-zipped them in the path 'C:\PROGRAMS\GCC' as opposed to the > recommended directory of 'C:\DJGPP'.

(But note that your version of EMM386 only supports 32MB of extended memory, instead of all the 48MB you have.) > My first problem was when I ran 'gcc', I got the following error > message: > GCC.EXE: installation problem, cannot exec 'cc1': No such file or > directory Add -v to the GCC command line and watch what does it say about the specs file. If it says "Using built-in specs", you have an installation problem that causes the above problem as well. > I found that CC1.EXE was not in the BIN directory but in: > \programs\gcc\lib\gcc-lib\djgpp\2.952\cc1.exe That is the correct place of cc1.exe; do NOT copy or move it anywhere else. > As a temporary measure, I copied CC1.EXE into the BIN directory and ran > 'gcc' again. This time I got the following error message: > GCC.EXE: installation problem, cannot exec 'cc1': Not enough memory > The CC1.EXE file is 1.8MB in size so it understandably won't load in > DOS's 640K base memory The size of the program on disk is not important, since it is loaded into extended memory, not into DOS memory. The memory size is not your problem. You need to find out why didn't GCC find cc1.exe when it was in the lib\gcc-lib\djgpp\2.952\ subdirectory. Please remove the copy of cc1.exe you put into bin for the rest of your digging into this problem. > I strongly suspect my problem has to do with the DJGPP.ENV file in the > \PROGRAMS\GCC directory which contains the following unmodified line: > DJDIR=%:/>DJGPP% > which needs to be modified to reflect my \PROGRAMS\GCC path No, please do NOT edit DJGPP.ENV. This line is correct: it tells DJGPP programs to compute the value of DJDIR by taking the leading directories part of the value of the DJGPP variable, and convert the backslashes into forward slashes while at that. In other words, in your case, DJDIR will have the value c:/programs/gcc, once you put the drive letter into the DJGPP variable. This is what the rest of DJGPP programs expect. > First, does anyone know how to edit the DJGPP.ENV file to reflect the > path I am using? Do NOT edit it! > Second, does anyone know why 'cc1' will not run? If the above doesn't help, add -v to the GCC command line, and post here everything that the compiler prints. > Am I terribly misinformed in thinking that 'gcc' runs under native > MS-DOS as opposed to a WIN95 DOS box or something? GCC can run in both environments: native MS-DOS and Windows DOS box.
