There seems to be an issue in the way -Ds in quotes are passed to the parser. Steps to reproduce: 1) Create HelloWorld program int main(void) DEFINED { puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */ return EXIT_SUCCESS; } 2) Add define (in build settings, or paths and symbols) DEFINED -> "" 3) Build the app make all Building file: ../src/parser_issue.c Invoking: GCC C Compiler gcc -DDEFINED="" -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/parser_issue.d" -MT"src/parser_issue.d" -o"src/parser_issue.o" "../src/parser_issue.c" Finished building: ../src/parser_issue.c Syntax error shown in the UI. Adding "#define DEFINED" to the source file resolves the issue local to the file.
Interestingly if I change the -D to just -DDEFINED the parser no longer complains but the compiler does: Building file: ../src/parser_issue.c Invoking: GCC C Compiler gcc -DDEFINED -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/parser_issue.d" -MT"src/parser_issue.d" -o"src/parser_issue.o" "../src/parser_issue.c" ../src/parser_issue.c: In function 'main': ../src/parser_issue.c:14: error: expected declaration specifiers before numeric constant ../src/parser_issue.c:17: error: expected '{' at end of input make: *** [src/parser_issue.o] Error 1 with --save-temps I see that -DDEFINED: gcc => #define DEFINED 1 CDT Parse log => DEFINED= -DDEFINED="": gcc => #define DEFINED CDT Parse log => DEFINED=""
Presumably make / the shell is resolving an empty quotes to nothing, so the compiler isn't seeing this -DDEFINED=. The workaround is to set DEFINED= in the build settings page. Unfortunately the Paths & Symbols page has two boxes: Name + Value. If you leave Value blank it just does -DDEFINED which is interpreted as -DDEFINED=1. Even with -DDEFINED=, exporting this setting doesn't seem to work right. You end up with -DDEFINED again.
FWIW, I managed to work round the problem by setting DEFINED to ${env_var:NULL} (NULL is not set to anything). This gets propagated through the project references okay, and I end up with 'DDEFINED= on the command line rather than just -DDEFINED.
