[gcc 4.0.2] explicit instantiation/extern template unsats on symbols defined later
----------------------------------------------------------------------------------
Key: STDCXX-57
URL: http://issues.apache.org/jira/browse/STDCXX-57
Project: STDCXX
Type: Bug
Components: Build
Versions: 4.1.2
Environment: gcc 4.0.2
Reporter: Martin Sebor
Assigned to: Martin Sebor
Priority: Critical
Fix For: 4.1.3
Linking with gcc 4.0.2 gives many unsats for member functions of class templates explicitly
instantiated in the library. For example:
gcc -c -I/build/sebor/dev/stdlib/include/ansi -D_RWSTDDEBUG -pthreads -D_RWSTD_USE_CONFIG
-I/build/sebor/gcc-4.0.2-15s/include -I/build/sebor/dev/stdlib/include -I/build/sebor/dev/stdlib/examples/include
-pedantic -nostdinc++ -g -Wall -W -Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long
/build/sebor/dev/stdlib/examples/tutorial/alg7.cpp
gcc alg7.o -o alg7 -pthreads -L/build/sebor/gcc-4.0.2-15s/lib -lstd15s -lsupc++ -lm
Undefined first referenced
symbol in file
std::basic_string<char, std::char_traits<char>, std::allocator<char> >::substr(unsigned
int, unsigned int) constalg2.o
ld: fatal: Symbol referencing errors. No output written to alg2
collect2: ld returned 1 exit status
make: *** [alg2] Error 1
