It seems not poosible to build one version gcc from another version of gcc. This is due to incompatibilities that arise due to changes in gcc releases. There seems to be a difference between traditional C and ISO C. The warning explains it all: > ./read-rtl.c:53: warning: traditional C rejects ISO C style function > definitions One way to get around this is to change you build environment. Try setting the variable CC in the make file to one of the below and see if it compiles fine. gcc -ansi -Wall -pedantic gcc -traditional -Wall -pedantic Another way would be what my debian is able to do for me: # gcc --version gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) # apt-get build-dep gcc-3.3 Reading package lists...
