url: liburl from Boost-1.83 is not built under MSYS2/MinGW-W64

When I try to build Boost I get the following message:

[...]

At the same time in the root source directory (where b2 is) files Worksboost_1_83_0builddirboostbin.v2libsurlbuildgcc-13releasethreadapi-win32threading-multivisibility-hiddenlibboost_url-mgw13-mt-x32-1_83.dll.a and Worksboost_1_83_0builddirboostbin.v2libsurlbuildgcc-13releasethreadapi-win32threading-multivisibility-hiddenlibboost_url-mgw13-mt-x32-1_83.dll are created.

It seems to be a forward slash/backslash issue – as far as I can see liburl is the only library which uses response files (.rsp) and generated response files use both types of slashes, while, I think, they should use only forward slashes.

Static version has similar problem:

Reported upstream as https://github.com/bfgroup/b2/issues/352.

The problem is with this line:

https://github.com/bfgroup/b2/blob/5dca2965cb083060137498d6581fcbfb9522cfbc/src/tools/gcc.jam#L1094

The final :E="$(>)" needs to be changed to :E="$(>:T)".

This fixes the static version. I don’t get an error while building the dynamic version, and the :T seems properly present there already, so I’m not sure why the above doesn’t work.

This sounds like a b2 issue for me. However, looking at gcc.jam, it doesn’t seem to be true that URL is the only library using response files. E.g. in

https://github.com/bfgroup/b2/blob/5dca2965cb083060137498d6581fcbfb9522cfbc/src/tools/gcc.jam#L1094

response files are used unconditionally.

So this same issue should occur with any compiled Boost library, and it’s odd if it indeed affects only URL.

I was using powershell, not a bash shell. However, I was using it as a conan package.

Under Windows, you should build b2 using bootstrap.bat instead of bootstrap.sh from a bash shell, in order for it to know that it’s running under Windows so that it can interpret \ as a directory separator.

I tried cmake and it works. And yesterday I tried to execute the error command manually and replace the backslashes to slash in the rsp file, b2 can compile successfully.
