I recently upgraded my Linux distribution which also upgraded my C++ compilers to gcc 11. Since then, I have troubles to compile with cuda (through Kokkos) a previous project (unchanged). But no problem when using OpenMPI and OpenMP. I t...
If no errors, then compiler is okay. g++ and gcc behave differently with source files with a file extension of.c g++ tries to compile .c files as as C++, not C. C syntax causes errors. Obviously because it is different from C++. Try this as a compile: g++ -std...

linker indicating that ‘-fpic’ does not work; in that case, recompile with ‘-fPIC’ instead. (These maximums are 8k on the SPARC, 28k on AArch64 and 32k on the m68k and RS/6000. The x86 has no such limit.) Position-independent code requires special support, and therefore works ...
For GCC 11, I've added four new warnings: -Wanalyzer-write-to-const -Wanalyzer-write-to-string-literal -Wanalyzer-shift-count-negative -Wanalyzer-shift-count-overflow Each of these corresponds to a pre-existing warning implemented in the C and C++ front ends, but with a "-Wanalyzer" pr...

To compile the above code into an executable named area in the current working directory use the-oswitch withg++: g++ area.cpp -o area If you want to take advantage ofccache, just prepend the above command withccache, as follows:
