Hi, I am working with one of the porting projects in migrating from compq to gcc on x86_64. I am facing this problem since a week. Please help. While I am compiling a source using gcc and when I run it am getting the floating point exception for the binary I have compiled using the following options : compile : /usr/bin/gcc -g -c -Wall -fPIC -I/home/vkatakam/dstars.2003.1.0_new/src/inc -I/home/vkatakam/dst.2003.1.0_new/inc -I../inc -I/home/vkatakam/dst.2003.1.0_new/inc.cludge dr_End2End.c -o dr_End2End.o dr_End2End.c: In function `main': dr_End2End.c:242: warning: implicit declaration of function `dc_End2End' dr_End2End.c:248: warning: implicit declaration of function `dc_PrintEnd2End' dr_End2End.c: At top level: dr_End2End.c:2: warning: `dr_end2end_c' defined but not used /home/vkatakam/dstars.2003.1.0_new/src/inc/db_rec.h:5: warning: `db_rec_h' defined but not used /home/vkatakam/dstars.2003.1.0_new/inc/mesglog.h:4: warning: `mesglog_h' defined but not used Linking: /usr/bin/gcc -o ../bin/dr_End2End dr_End2End.o -L/home/vkatakam/dstars.2003.1.0_new/lib -L/home/vkatakam/dstars.2003.1.0_new/src/lib -L/oracle/app/oracle/product/10.1/lib -L/home/vkatakam/tmp/2003.1/lib -lMesgLog -lFileUtil -lc -lrt -lm -lclntsh -ldc_st -ldc_date -ldc_util -lsc_report -ldc_end : I am using the following: gcc -v Reading specs from /usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --host=x86_64-redhat-linux Thread model: posix gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-53) and the hardware is SMP Wed Jan 11 18:35:39 EST 2006 x86_64 x86_64 x86_64 GNU/Linux The ldd and nm tools on the binary are all ok and there are no undefined symbols. I have tried all options. some suggested to use x86_6 options. But i do not know how to use. Any suggestion is appreciated. Regards, Vivek
