[install] cygwin

SabreRunner opened this issue 5 months ago · 3 comments

The environment I'm running in is Unity's Build Automation. I need it to work for Mac/ios and Windows/Android builds but I'm currently focusing on Android in Cygwin. Since I don't control the environment, I don't know if I can even break out of cygwin. If there's any other commands I can try and get more info, let me know. Of course, attached below, is all the info I have.

Have you read and followed the installation tutorial at http://www.nokogiri.org/tutorials/installing_nokogiri.html?

[✔] Yes!

What is the complete output of gem install or bundle install?

Not available.

If installation failed during compilation, what are the complete contents of the mkmf.log file generated during the failed installation?

@SabreRunner Hi. I'll try to help you get this installed.

From your mkmf.log:

[error] conftest.c:4:10: fatal error: iconv.h: No such file or directory

It seems like iconv isn't installed on this machine. Cygwin seems to have a package that you may be able to install:

https://www.cygwin.com/packages/summary/libiconv.html

But alternatively, there is also a cygwin package available for nokogiri that you may want to try installing instead and avoid the entire compilation step?

https://cygwin.com/packages/summary/ruby-nokogiri.html

Answer 2 · 2024-04-22T08:17:13.000Z

I tried installing the libiconv package but that had a different problem.

Answer 3 · 2024-04-22T20:23:06.000Z

@SabreRunner You may want to try to ask this question on a cywin-specific forum. I'm not sure I can help you without more information.
