I have tried many times and with differents versions and downloads, but the problem allways happens. When I started ./configure, with or without parameters, the following message is displayed: (...) checking for gcc option to accept ANSI C... none needed checking for ranlib... ranlib checking whether gcc and cc understand -c and -o together... yes checking whether ln -s works... yes checking for flex... lex checking for yywrap in -ll... no checking lex output file root... ./configure: lex: command not found configure: error: cannot find output from lex; giving up I read the config.log and the last lines are: (...) configure:2209: cc -c conftest.c -o conftest.o 1>&5 configure:2236: checking whether ln -s works configure:2260: checking for flex configure:2294: checking for yywrap in -ll configure:2313: gcc -o conftest -g -O2 conftest.c -ll 1>&5 /usr/i386-slackware-linux/bin/ld: cannot open -ll: No such file or directory collect2: ld returned 1 exit status configure: failed program was: #line 2302 "configure" #include "confdefs.h" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char yywrap(); int main() { yywrap() ; return 0; } configure:2337: checking lex output file root Could someone help me? What is the problem? What I have to do to correct this? Thanks a lot.
