hi Group, Just updated gcc and ran into a problem $gcc -v Using built-in specs. Target: i486-linux-gnu Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-targets=all --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu Thread model: posix gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3) My test file try.c $cat try.c typedef struct { int j; float k; char l; } MyStruct; main() { MyStruct s = { 1, 3.2, 'a'}; } $gcc -fdump-translation-unit try.c generates try.c.001t.tu (earlier versions generated try.c.tu). I don't see any reference of MyStruct in the generated file. Please help, am I missing any thing in the process? --regards, Praveen
