Dear GHC team, I again have problems with making GHC from source. Now, this is for making ghc-6.9.20080910-src.tar.bz with ghc-6.8.3. ./configure --prefix=... reports that Happy is needed. But earlier, I compiled ghc-6.8.3 with itself, and it did not required Happy. Generally, as I recall, I got used to making GHC from source without installing Happy. Please, what (and why) has changed about this? Maybe ghc-6.8.3 has Happy inside it and ghc-6.9.20080910-src has not? Here are the fragments of config.log for ghc-6.8.3 auto-make: --------------------------------------- ... It was created by The Glorious Glasgow Haskell Compilation System configure 6.8.3, which was generated by GNU Autoconf 2.59. Invocation command line was $ ./configure --prefix=/home/mechvel/ghc/6.8.3/inst ## --------- ## ## Platform. ## ## --------- ## hostname = scico uname -m = i686 uname -r = 2.6.22-1-686 uname -s = Linux uname -v = #1 SMP Mon Jul 23 13:23:02 UTC 2007 /usr/bin/uname -p = unknown /bin/uname -X = unknown /bin/arch = unknown /usr/bin/arch -k = unknown /usr/convex/getsysinfo = unknown hostinfo = unknown /bin/machine = unknown /usr/bin/oslevel = unknown /bin/universe = unknown PATH: /home/mechvel/ghc/6.8.3/inst1/bin ... ... configure:5565: result: /home/mechvel/ghc/6.8.3/inst1/bin/ghc-pkg configure:5707: checking for happy configure:5740: result: no configure:5744: checking for version of happy configure:5757: result: configure:5794: checking for haddock configure:5827: result: no configure:5837: checking for alex configure:5870: result: no configure:5874: checking for version of alex configure:5887: result: ... ... #define _FILE_OFFSET_BITS 64 configure: exit 0 --------------------------------------------------------------- Why ghc-6.9.20080910-src.tar.bz cannot produce such? What I am missing? Can you somehow preserve the `make' procedure between the versions? Second, several years ago I was able to `make' Happy. Now, I tried to make Happy-1.17, with ghc-6.8.3. But it occurs difficult to find out how to do this. This is not like with GHC. The source GHC has README in the root of the `make' directory, where it is visible an short instruction ./configure ... make make install And in Happy, I do not find such. I am unhappy with Happy. Please, advise, ----------------- Serge Mechveliani mechvel@botik.ru
