X has nothing to do with this. Run this test: junior:ghc-6.8.1 joelr$ nm compiler/stage2/ghc-6.8.1|grep _environ 008f7e10 T ___hscore_environ 00a40004 D _environ The symbol is there (D). Now run the same on /usr/local/lib/ghc-6.8.1/ ghc-6.8.1, assuming you installed into /usr/local. The symbol will _not_ be there. What's going on? Take a look: junior:ghc-6.8.1 joelr$ strip compiler/stage1/ghc-6.8.1 junior:ghc-6.8.1 joelr$ nm compiler/stage1/ghc-6.8.1|grep _environ junior:ghc-6.8.1 joelr$ Now you see it and now you don't. install-sh has a '-s' option that runs strip on the installed binaries. To work around the problem either copy the binaries from stage2 manually or find the Makefile that runs install-sh -s and remove the strip option. On Nov 9, 2007, at 9:24 PM, Deborah Goldsmith wrote:
I'm seeing this, too. An fgrep of /usr/include for environ picked up this:
/usr/include/X11/Xw32defs.h:#define environ _environ
Is there any reason this X11 header would get included? That would mess up this in HsBase.h:
/* ToDo: write a feature test that doesn't assume 'environ' to * be in scope at link-time. */ extern char** environ; INLINE char **__hscore_environ() { return environ; }
