Hello, I am brand new to linux/unix and I am trying to install a program that requires gfortran. My understanding is that gfortran is part of gcc, and that I therefore need to install gcc to run it. I have been having some problems accomplishing this, however. I have downloaded the source, and (I think) installed all the prerequisite programs. The configure runs just fine, but when I try to build the program, it runs for several minutes before giving the following error: checking for x86_64-unknown-linux-gnu-gcc.../home/afkoeppel/objdir/.gcc/xgcc -B/home/afkoeppel/objdir/./gcc -B/home/afkoeppel/gcc-install//x86_64unknown-linux-gnu/lib/ -B/home/afkoeppel/gcc-install//x86_64unknown-linux-gnu/include -isystem /home/afkoeppel/gcc-install//x86_64unknown-linux-gnu/sys-include checking for suffix of object files... configure error: in '/home/afkoeppel/objdir/x86_64unknown-linux-gnu/libgcc': configure: error: cannot compute suffix of object files: cannot compile see 'config.log' for more details. make [2]: ***[configure-stage1-target-libgcc] Error 1 make [2]: Leaving directory '/home/afkoeppel/objdir' make [1] ***[-stage1-bubble] Error 2 make [1]: Leaving directory '/home/afkoeppel/objdir' make; *** [all] Error 2 I followed the suggestion to look in config.log, but my comprehension is too limited at this point to make any sense of what I'm finding there. Searching for the error here I found the suggestion that adding gmp and mpfr to the LD_LIBRARY_PATH might solve the problem. http://old.nabble.com/-Bug-bootstrap-35577---New:-configure:-error:-cannot-compute-suffix-of-object-files-td16038190.html http://old.nabble.com/-Bug-bootstrap-35577---New:-configure:-error:-cannot-compute-suffix-of-object-files-td16038190.html I tried this, but I'm not entirely sure if I've done it correctly, and I am still getting the same error. I've attached my config.log file to this post, and I'm hoping someone will be able to help me figure out what I've been doing wrong. I apologize if the error is something very basic, or very stupid, or covered thoroughly here already and I just missed it. Thanks in advance for any help anyone can provide. http://old.nabble.com/file/p27520625/config.log config.log -- View this message in context: http://old.nabble.com/Help-building-gcc-tp27520625p27520625.html Sent from the gcc - Help mailing list archive at Nabble.com.
