7488 :: TA functions in NIM

• Pumpus (orginal) [2021-02-08T23:37:48+01:00] view original

  Hi Nim people!

  I have successfully compiled the TA example shown here in Windows

  https://www.ta-lib.org/d_api/ta_initialize.html

  I'm capable even to really use the TA functions, not only initializing as described here: https://www.ta-lib.org/d_api/d_api.html

  This is done in C!

  I'm on Windows. I have downloaded precompiled binaries ta-lib-0.4.0-msvc.zip here:

  https://www.ta-lib.org/hdr_dw.html

  I'm compiling my C example described above and called ta.c like this:

   batch
  C:\Users\<me>\Desktop\NIM32\mingw32\bin\gcc.exe -c  -I "C:\ta-lib\c\include"  ta.c
  C:\Users\<me>\Desktop\NIM32\mingw32\bin\gcc.exe -o ta.exe    ta.o   -L "C:\ta-lib\c\lib" -l ta_libc_cdd  -l ta_libc_cdr
  Run

  Note: C:ta-libcinclude contain headers C:ta-libclib contain precompiled static libraries

  I'm using a 32 bit gcc in an isolated folder (not on system path) and everything is working fine. Compiler warns that they are static VS .lib libraries instead of .a, but I repeat everything is fine.

  A question that arise naturally. How to do it in NIM?

  Here is how I want to compile against static C libraries with a 32 bit compiler my quasi-empty ta.nim source file (probably wrong):

   batch
  nim c --gcc.path=C:\Users\<me>\Desktop\NIM32\mingw32\bin  --cpu:i386 --dynlibOverrideAll -r ta.nim --passL="-L "C:\ta-lib\c\lib"" --passL="-l ta_libc_cdd"  --passL="-l ta_libc_cdr" --passC=" -I "C:\ta-lib\c\include""
  Run

  My ta.nim file in is quiet empty for the moment I say, except a hello world and a headache-try to link the h header for what I've seen in the documentation and forum...Probably I'm doing wrong...

  {.header: "C:/ta-lib/c/include/ta_libc.h"}
  {.link: "C:/ta-lib/c/lib/ta_libc_cdd.lib"}
  {.link: "C:/ta-lib/c/lib/ta_libc_cdr.lib"}
  
  
  echo "hello world"
  Run
