[htoolkit-users] Problem with HSQL

[Robert v. H. <rh...@cs...>]

Hi all,

I am experiencing a problem building HSQL on SuSE 9.2, GHC 6.2.2.

I checked out HSQL from cvs, did
 ./configure --enable-mysql --prefix=/home/robert/soft
 make install

This seemed to go perfectly. Configure told me
 MySQL:       yes
 PostgreSQL:  no
 SQLite:      no
 ODBC:        no
which was what I wanted.

However, when I do ghci -package hsql, I get:
 Loading package base ... linking ... done.
 Loading package hsql ... ghc-6.2.2: can't load .so/.DLL for: c 
(/usr/lib/libc.so: invalid ELF header)

Do you have any idea what might be wrong?

Thanks,
Robert

I belive you are the second person in the world to see this error. If=20
you Google for it, all you get is a log of me asking about it in the=20
#haskell irc channel. The problem is that for some reason, on some=20
machines mysql-config reports that it needs -lc. This means that=20
/usr/lib/ghc-6.2.2/package.conf will have "c" in extra_libraries, which=20
means that ghci will try to load libc.so. This is completely redundant,=20
and causes the error above. The simplest solution is to hand-edit=20
package.conf after installing HSQL and remove "c" from extra_libraries=20
in the hsql section. We should probably put a fix for this in the=20
configure script.
