Package: unixodbc
Version: 2.2.4-11
Severity: important
Tags: patch
When the unixodbc package is built, the SHLIBEXT C pre-processor macro
is not defined. (I believe this is because the libltdl library is
intentionally not built by the Debian package, although I haven't tested
this hypothesis.) The lack of definition may be seen in the buildd logs
by searching for "SHLIBEXT":
http://buildd.debian.org/fetch.php?&pkg=unixodbc&ver=2.2.4-11&arch=i386&stamp=1097873269&file=log&as=raw
Because SHLIBEXT is not set, code in DriverManager/SQLConnect.c attempts
to load a file named "/usr/lib/libodbccr.1" at runtime (which obviously
doesn't exist) instead of "/usr/lib/libodbccr.so.1". I ran into this
while trying to configure phpbb2 to connect to a SQL Server 2000
database via ODBC. The initial error looked like this:
Warning: odbc_connect(): SQL error: [unixODBC][Driver Manager]Can't open
cursor lib 'libodbccr' : /usr/lib/libodbccr.1: cannot open shared object
file: No such file or directory, SQL state 01000 in SQLConnect in
/usr/share/phpbb2/site/db/mssql-odbc.php on line 54
The attached patch fixes the build-time issue by modifying configure.in
and configure to simply use the $shrext variable which is set for all
configurations anyway. This forces SHLIBEXT to be defined during build
time. (NOTE: I tried re-running autoconf[2.*], but unixodbc has trouble
finding X libraries while running "configure" after doing this.)
Alas, this change did not fix the problem I was seeing with phpbb2. :(
