My configure on 'master' fails with the following. I need to link with -lfl to get the symbol yywrap. I don't know why we haven't been encountering this before.
Error running make; make install on c2html: Could not execute "cd /home/jed/petsc/mpich-optg/externalpackages/c2html-0.9.4 && make && make install && make clean": flex ./c2html.l gcc -O -I. -I. -DCOMPRESSION=1 -o c2html lex.yy.c ./mymain.c ./colors.c Makefile:67: recipe for target 'c2html' failed/tmp/ccFJeTaT.o: In function `yylex': lex.yy.c:(.text+0x334d): undefined reference to `yywrap' collect2: error: ld returned 1 exit status make: *** [c2html] Error 1 . Try disable c2html with --with-c2html=0 ******************************************************************************* Solution is to pass LEXLIB=-lfl to c2html's configure, though I don't know if we need to test for -lfl first (AFAIK, it's a standard part of the flex distribution). Also note that there is a newer c2html. https://aur.archlinux.org/packages/c2/c2html/PKGBUILD
