I’m unable to get Travis to compile:
- export PLATFORMIO_BUILD_FLAGS="-D TEMPLATE_PLACEHOLDER='~'" in my travis.yml.
The build environment recognizes this but doesn’t understand the new value of the #define. The build then fails because in the source lib it has
I want to make it as if it was
#define TEMPLATE_PLACEHOLDER '~'
What it the correct syntax to have a build flag with single quotes?
