Date: Fri, 18 Jun 2004 23:34:05 +0200 Mime-Version: 1.0 Content-Type: text/plain; format=flowed Message-ID: X-OriginalArrivalTime: 18 Jun 2004 21:34:06.0131 (UTC) FILETIME=[FB751830:01C4557B] I'm trying to build a simple app under cygwin using the windows version of mySQL server. If I compile with "gcc -I/cygdrive/c/mysql/include -L/cygdrive/c/mysql/lib/opt -lmysql myTest.c -o myTest.exe" then my program compiles, links and even runs, but then core dumps. The result are very strange. But while looking around on google and this mailing list, I learned that I should use a mySQLclient library that was compiled under a current cygwin. OK I've done that (./configure --without-server;make;make install), but now I get errors when I try compiling my app. gcc (actually ld) cannot find -lmySQL or undefined references when linking with -lmysqlclient. gcc -I/usr/local/include/mysql -L/usr/lib -L/usr/local/lib/mysql -lmysqlclient myTest.c -o myTest.exe /cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0xdf):myTest.c: undefined reference to `_mysql_init' /cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0x138):myTest.c : undefined reference to `_mysql_real_connect' /cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0x1b0):myTest.c : undefined reference to `_mysql_query' /cygdrive/c/DOCUME~1/ESA3BD~1.NEW/LOCALS~1/Temp/cc25Xged.o(.text+0x224):myTest.c : undefined reference to `_mysql_close' collect2: ld returned 1 exit status make: *** [myTest.exe] Error 1 OR gcc -I/usr/local/include/mysql -L/usr/lib -L/usr/local/lib/mysql -lmysql myTest.c -o myTest.exe /usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../../i686-pc-cygwin/bin/ld: cannot find -lmysql collect2: ld returned 1 exit status make: *** [myTest.exe] Error 1 I've tried downloading a prebuilt mysql library from a german site (Sorry I forgot the name). But the same problem occurs. I've updated my cygwin install with the latest stuff, but that didn't help either. What am I doing wrong?
