Thanks to Juergen Hunold's help, I was able to build Boost 1.36 on Linux-x86-32bit with gcc and stlport However, the boost lib seems to links against both "libstlport_gcc.so" and "libstdc++.so.5". See line 1 and line 3 below Should it not be linking only against "libstlport_gcc.so"?? ldd libboost_unit_test_framework-gcc32-mt-p-1_36.so Line 1: libstlport_gcc.so => /somepath/STLport-4.6.2/lib/libstlport_gcc.so (0xb74d9000) Line 2: librt.so.1 => /lib/tls/librt.so.1 (0xb74c5000) Line 3: libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0xb7412000) Line 4: libm.so.6 => /lib/tls/libm.so.6 (0xb73f0000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb73e6000) libpthread.so.0 => /lib/tls/libpthread.so.0 (0xb73d6000) libc.so.6 => /lib/tls/libc.so.6 (0xb729e000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) Thanks, Diwakar (Extn. 64048) ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ==============================================================================
