you need "#define USE_FULL_ERROR_LIST 1", because
` const char * SCPI_ErrorTranslate(int16_t err) {
switch (err) {
#define X(def, val, str) case def: return str;
#if USE_FULL_ERROR_LIST
#define XE X
#else
#define XE(def, val, str)
#endif
LIST_OF_ERRORS

#if USE_USER_ERROR_LIST
LIST_OF_USER_ERRORS
#endif
#undef X
#undef XE
default: return "Unknown error";
}
}

thanks for the info but adding USE_FULL_ERROR_LIST 1 is not enough for get the list of error.

I have tried all method explained on this case without success:
#107

I need to pass the information USE_FULL_ERROR_LIST 1 to the compiler to have the X-macro to be processed.

For now, my makefile perfom the action below without processing the X-macro.

My final goal is to include my own list of errors USE_USER_ERROR_LIST 1.

Makefile.txt
{{{{
add_definitions(-DSCPI_USER_CONFIG=1) #DL flag to add scpi_user_config.h

Build the SCPI parsing library (a Git submodule) as an external project.

We'll build it in its source directory using its own Makefile, then place the

.a file and the library's headers in scpi-parser for including/linking it.

include(ExternalProject)
set(scpi_parser_SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/lib/scpi-parser/libscpi")
set(scpi_parser_PREFIX "${CMAKE_CURRENT_BINARY_DIR}/scpi-parser")
ExternalProject_Add(scpi_parser_build
SOURCE_DIR "${scpi_parser_SOURCE_DIR}"
BUILD_IN_SOURCE ON
CONFIGURE_COMMAND make clean
# Only generate the static version of the library, not the shared one (doesn't make sense here).
BUILD_COMMAND env "CC=${CMAKE_C_COMPILER}" "CFLAGS=${CMAKE_C_FLAGS}" "PREFIX=${scpi_parser_PREFIX}" make static
INSTALL_DIR "${scpi_parser_PREFIX}"
INSTALL_COMMAND cp -r "${scpi_parser_SOURCE_DIR}/dist/libscpi.a" "${scpi_parser_SOURCE_DIR}/inc" "${scpi_parser_PREFIX}"
)
}}}}}

Hope that's help to understand my problem.
