    Okay so I was digging deeper in the .pro file and I found these few lines of code at the bottom. It seems this is where the error is originating from. I believe these are different build rules depending on the environment, I am still not sure what is the problem

      Hi,

      Do you have that static library available in the project sources ?

        @SGaist I do have the header file ftd2xx.h. However, I do not have the compiled static file libftd2xx.a. On my Windows machine, I think (and I might be wrong) the library is being compiled at run time because I just checked there and only the header file is available in the project sources.

          In that case you should first get the library for your OS.

            @SGaist I installed the libftd2xx.a static library and copied it into usr/lib as well as usr/local/lib and I am getting the same error. Am I missing something?

              The PRE_TARGETDEPS points within your sources.

              One thing you can do is comment out this line.

              It's usually used to ensure that if a static library is changed, then it will trigger a rebuild of the target. In your can you do not seem to build libftd2xx so you should be safe from that point of vue.

                @SGaist I commented out the line you mentioned, and now I get a bunch more errors relating to that same library. Seems to be originating from line above the one I removed:
                /usr/bin/ld: skipping incompatible /usr/local/lib/libftd2xx.so when searching for -lftd2xx
                /usr/bin/ld: skipping incompatible /usr/local/lib/libftd2xx.a when searching for -lftd2xx
                /usr/bin/ld: cannot find -lftd2xx

                  You are missing the OpenGL development package for your distribution.

                  You likely have a 32bit build of ftd2xx.

                    @SGaist Awesome, you were right. Now with the 64bit ftd2xx and OpenGL package installed, it builds and runs. I guess I'll leave that last line commented out until I figure out the problem with it.

                    Thanks for your help, highly appreciated.

                      @Adham said in Compile error when building project (process: "/usr/bin/make" -j8):

                      As I wrote before, this line expects to find the static libftd2xx library file within the project sources.

                        @SGaist I heard you, I tried throwing it in there but I got the same error. Anyways I should be good for now. I'll come back if I can't figure it out later on lol. Thanks again.
