" I have the strong Impression that all this stuff is very new to you. " <------ it's not new, I just compiled with the same command in windows7 and it worked ok. I'm just an old layman on this. About your 3 questions, i just installed the libsndfile from mega-nerd and installed it in the same way as in windows7, and i have no idea why it does not work in windows10. ________________________________ From: music-dsp <[email protected]> on behalf of Simon Fly <[email protected]> Sent: Sunday, December 6, 2020 5:36 PM To: [email protected] <[email protected]> Subject: AW: libsndfile-1.dll: file not recognized: file format not recognized
Hey, I don’t want to discourage you, but looking at how you constructed the first Compiler command, I have the strong Impression that all this stuff is very new to you. So let me give you some Questions ( Facts to consider before you move on. 1. G++ / gcc is a Compiler primarly meant for UNIX based operating Systems, i.e. Ubuntu etc. Programs compiled for unix CANNOT be simply copied over to Windows and run natively there, or vice versa. MSVC is what you probably want to use when directly Building for Windows. You’ll probably want visual Studio or visual Studio Code with that to get you started. That being said, g++ CAN be used for „cross-compiling“, but it’s an advanced Topic. 2. Dynamic libraries are not trivial, especially when writing for first program. If you are completely new to this, I urge you to take into account a relatively steep learning curve, and the time it takes to get over it. 3. Are you sure you got the Right Tools for what you want to do? perhaps a simple python script is much easier to get running and does the same Job. Best of luck, .

I got no answer from Erik Castro Lopo, no answer from the forum of the site from where libsndfile is downloaded. I got one answer from someone from this forum and the csound forum and it was not useful. So i begin to install linux ubuntu in VM and i'll try to transfer files between VM and windows10...

Could you make sure the DLL is compatible with your OS? Also, it maybe cannot hurt to remove previous object files - if there are any. Best, Matthias Am So., 29.

Since you didn't use the "-l" option, gcc assumes that libsndfile-1.dll is a plain-text source code file. Since it is a binary file, not a plain-text file, gcc has trouble processing it. A first reference for you to solve this problem may be https://stackoverflow.com/questions/17968801/link-against-a-windows-dll-lib-file-combination-with-gcc-under-cygwin/34902737#34902737.
