MacOS

Hi,

I tried to install on MacOS but make failed because :

Scanning dependencies of target CppLinuxSerial
[ 10%] Building CXX object src/CMakeFiles/CppLinuxSerial.dir/SerialPort.cpp.o
/tmp/CppLinuxSerial/src/SerialPort.cpp:23:10: fatal error: 'asm/ioctls.h' file not
      found
#include <asm/ioctls.h>
         ^~~~~~~~~~~~~~
1 error generated.
make[2]: *** [src/CMakeFiles/CppLinuxSerial.dir/SerialPort.cpp.o] Error 1
make[1]: *** [src/CMakeFiles/CppLinuxSerial.dir/all] Error 2
make: *** [all] Error 2

do you know why ? or how I can fix it ?

Thanks

Hi there @dupuysylvain . I have an idea. Please comment out that include line in the source code, then make and install the library again. I did some really basic testing on Xubuntu 18.04 (I don't have a Mac sorry) and I seemed to be able to compile just fine without this header file. Let me know if this works.

Hi,

thanks for the response, I tried comment the two "asm/' include, I have new set of errors :

//#include <asm/ioctls.h>
//#include <asm/termbits.h>

make[1]: *** [src/CMakeFiles/CppLinuxSerial.dir/all] Error 2

For now, I used the tag v2.0.3 to make it work.

I have another question, do you know how to include the library in a cmake project (with CMakeLists.list) ?

Thanks for your help

Hi @dupuysylvain , I tried removing all use of the termios2 struct to make it MacOS compatible, however I lost the ability to set custom baud rates correctly in Linux when doing so. Given this library's primary focus is Linux, I'm going to leave the custom baud rate functionality in for now sorry.
