I've been having a bit of trouble compiling ghc5.02 from source on Solaris 2.6. The problem is that it can't find readline/readline.h which is not in a standard place since I had to compile readline myself. I've been messing around with various environment variables and configuration options, but have failed so far to communicate where this file is. I'm hoping someone can give me a suggestion. (I've reviewed the mailing list log and FAQ and have seen that readline is a problem on Solaris, but haven't seen anything that obviously is what I've been missing.)
I hacked mk/config.mk to say GhcLibsWithReadline=YES, since I have libreadline.a and libtermcap.a in my LD_LIBRARY_PATH.
BTW: the "right" way to modify these variables is by overriding them in your build.mk file, since config.mk is auto-generated every time you run configure.
That produced the aforementioned missing readline/readline.h. I tried CFLAGS=<blah> so that readline/readline.h should be visible but that didn't work either.
You can set ReadlineIncludePath in build.mk to the path containing readline/readline.h.
One more thing, is there a particular version of readline I should be using? (I'm using 4.2)
4.2 should be fine. Cheers, Simon
