I configured gcc-4.5.0 using the command $. <path_to_gcc-4.5.0/configure> --enable-languages=c --prefix=<absolute_path_of_install_folder> followed by $. make; $. make install; The installation proceeded without any errors. However, while running make check in gcc folder of build directory, I get the following error: make[1]: [check-parallel-gcc] Error 1 (ignored) The summary of make check is : === gcc Summary === # of expected passes 62284 # of unexpected failures 13 # of unexpected successes 25 # of expected failures 192 # of unsupported tests 533 What is the meaning of the Error? Is something wrong in my way of doing make check? -- With regards, Prashant Singh Rawat http://www.cse.iitb.ac.in/~prashantr
