I have created an application using the AMDTPowerProfileAPI api in AMD_CodeXL_Linux_x86_64_1.8.9654/SDK/AMDTPowerProfile/bin/x86_64/

When I attempt to link with libAMDTPowerProfileAPI.so, I get linker errors:

./lib/libAMDTPowerProfileAPI.so: undefined reference to `osCriticalSectionLocker::osCriticalSectionLocker(osCriticalSection&)'

./lib/libAMDTPowerProfileAPI.so: undefined reference to `osCriticalSectionLocker::leaveCriticalSection()'

./lib/libAMDTPowerProfileAPI.so: undefined reference to `osCriticalSectionLocker::~osCriticalSectionLocker()'

./lib/libAMDTPowerProfileAPI.so: undefined reference to `osCriticalSection::osCriticalSection()'

./lib/libAMDTPowerProfileAPI.so: undefined reference to `osCriticalSection::~osCriticalSection()'

collect2: error: ld returned 1 exit status

I would call this a bug. Please may I have the correct linker flags to use this library. It is not given in the documentation.

Thanks.

Hi,

Since AMDTPowerProfileAPI.so has depenedencies on
AMDTOSWrappers and AMDTBaseTools shared libraries we are getting this errors.
These shared library is located in AMD_CodeXL_Linux_x86_64_1.8.9654 directory.

Assuming test program is located in
AMD_CodeXL_Linux_x86_64_1.8.XX/SDK/AMDTPowerProfile/bin/x86_64 directory as
test.cpp and we are also executing from the same directory, we can perform the
following steps to execute the test code.

1. Set the LD_LIBRARY_PATH.

              
export LD_LIBRARY_PATH=export LD_LIBRARY_PATH=../../../../

1. Set the linker flags

              
g++ test.cpp -I../../inc/ -L. -lAMDTPowerProfileAPI -L../../../../
-lAMDTOSWrappers -lAMDTBaseTools -o test

1. Execute

              
./test
