CMakeLists.txt uses set(CMAKE_DEBUG_POSTFIX "d") to distinguish
between debug and release lib. Use this postfix also in the
generated tinyxml2.pc file in case of a CMake Debug build.
This results in the following contents of tinyxml2.pc
- Release:
Libs: -L${libdir} -ltinyxml2
- Debug:
Libs: -L${libdir} -ltinyxml2d
I compiled tinyxml2 with the following changes to CMakeLists.txt:
-------------------------------------------------- ------------------------------------------
set (CMAKE_C_COMPILER "/ usr / local / bin / clang10")
set (CMAKE_CXX_COMPILER "/ usr / local / bin / clang ++ 10")
add_compile_options (-g)
add_compile_options (-fsanitize = address, undefined, integer, alignment, bool, builtin, bounds, enum, function, nonnull-attribute, null, object-size, pointer-overflow, return, returns-nonnull-attribute, unreachable, vla-bound , vptr)
set_source_files_properties (tinyxml2.cpp tinyxml2.h
PROPERTIES COMPILE_FLAGS -fsanitize = address, undefined, integer, alignment, bool, builtin, bounds, enum, function, nonnull-attribute, null, object-size, pointer-overflow, return, returns-nonnull-attribute, unreachable, vla-bound , vptr)

(Sorry for the dirty code.)
And launched the xmltest utility:

Also, the comparison between size_t max and the actual file size is done
as an unsigned long long, since that type is guaranteed to be at least
64 bits, even on a 32-bit architecture.
