[fpc-pascal] USB Human Interface Devices

[James Richters]

I am trying to compile this with a stock installation of FPC 3.0.4 for windows… which does not have 64bit.. it only installs i386-win32 and then there is a cross compiler for x86_64-win64

 

I started with the zip file at:

https://github.com/jsuzineau/pascal_o_r_mapping/releases/tag/pas-libusb_convenience_release_2

 

then I created an lib\i386-win32 subdirectory 

then from this subdirectory:  I:\Programming\pas-libusb_test_dll\src\examples> 

I used this command line:

I:\Programming\FPC\3.0.4\bin\i386-win32\fpc.exe -MObjFPC -Scghi -O1 -g -gl -l -vewnhibq -Filib\i386-win32\ -Fu.. -Fu. -FUlib\i386-win32\ -FE. -otest1library.exe test1library.pas

 

Here is the output:

 

Hint: (11030) Start of reading config file I:\Programming\FPC\3.0.4\bin\i386-win32\fpc.cfg

Hint: (11031) End of reading config file I:\Programming\FPC\3.0.4\bin\i386-win32\fpc.cfg

Any ideas?  Is this just from using i386-win32? Maybe the DLL is only for 64bit? Maybe some completely unrelated issue?  If 64bit is needed, what’s the best way to install FPC3.0.4 for x86_64-win64?  It seems like I tried to do that before and it wasn’t really very easy to try to learn how to compile it.

I verified, test1library can be build with this command line:

C:\lazarus\fpc\3.0.4\bin\x86_64-win64\fpc.exe -MObjFPC -Scghi -O1 -g -gl -l -vewnhibq -Filib\ x86_64-win64 -Fu.. -Fu. -FUlib\x86_64-win64 -FE. -otest1library.exe test1library.pas

(eventually you need to create subdirectory lib\x86_64-win64 by hand)
