9880 :: Trouble compiling libraries with cpp header

• francisl (orginal) [2023-02-10T19:50:41+01:00] view original

  Hi,

  I have a project I started 2 years ago to create a web view binding to and updated version of 'webview'. https://github.com/francisl/webview

  The compilation was working fine, but when I try update the code I start having issues.

  • while using the nimble command to run the example it was loading the mais webview.nim from another clone directory
  • cleaning the cache create and not using -p:./src cause the example program failing finding the webview.nim
  • Now it can't find the header files. Even when I pass --cincludes:./webview https://github.com/francisl/webview/blob/main/webview.nimble#L26

  now I have

  
  CC: minimal.nim
  ~//.cache/nim/minimal_d/@mminimal.nim.cpp:8:10: fatal error: 'webview.h' file not found
  #include "webview.h"
           ^~~~~~~~~~~

  Any hint on how I can solve that issue?

  Now it can't find the header files

  Try using an absolute path.

  @sls1005 is right. --cincludes requires an absolute path. Alternatively, this seems to work:

  nim cpp -p:./src --passC:"-I./webview" --run examples/minimal/minimal.nim
  Run

  For the -p problem, you need to put a config.nims in your examples/ folder with the content if you don't want to use -p:

  # config.nims
  --path:"../src"
  Run

  I got it working with --passC:"-I./webview"

  But I can't make it work with an absolute path.

  Thanks for the help.
