path problem when file reading Topic is solved

[dsdanielko]

I have run into a problem with the compiled binary and directories/paths.

Although the source file is stored in the folder 'src' in the project folder, it seems any paths for file I/O in the code is done relative to the parent project folder and not 'src' folder. This leads to the undesired behavior where even the compiled binary processes any paths as being relative to the parent folder of the folder that contains the binary.

Is there a way to set the working directory to be where the binary is stored and not its parent folder?

Kind of hard to explain but if you have the binary stored like this:

Folder 1
|-Folder 2
|-|-binary.xe
|-|-file.txt

and if binary.xe has:

Code: Select all

fd = _open("file.txt", O_RDONLY, 0);

_open fails because "file.txt is in Folder 2 instead of Folder 1.
If file.txt was moved to Folder 1, the _open succeeds.

Please help.
Thanks

Update: It seems I was mistaken. The paths seem to be relative to whereever you use xrun from. In my case I call xrun from a batch file in folder 1 which is why I am getting this behavior i believe.

Is there a way to change the relative path to folder 2?

You could just build the path relative to your running folder. ../ would be up one directory. If your tree is right you could just just /folder2/file.txt but you should make sure every folder name is simple as possible, I'm not sure what convention they use, it may have limited #of characters for file names and directories. Try it and if it isn't working you'll have to figure out what the names are actually seen as.

Sadly folder 2 is not the only folder in folder 1. Folder 1 contains Folder 2, 3, 4 and so on until 32. Furthermore, each folder contains the same binary.xe but a unique file.txt. So I cannot hardcode the path as /folder2/file.txt since every other binary.xe would then check the folder 2 file.txt

Change the current directory before calling xrun:

Code: Select all

REM setup environment
call "C:\Program Files (x86)\XMOS\xTIMEcomposer\Community_14.1.2\SetEnv.bat"
cd "Folder 2"
xrun binary.xe
cd ../"Folder 3"
xrun binary.xe
