Can you explain, what you're trying to do?

[yunkyukim]

I'm trying to make my github.io using jekyll-theme-chirpy.

The "Steps to reproduce" above are an important part of a bug report. No one can help you, if you don't tell the command(s) you executed and the output text of them.

I just did an successful jekyll install - it looks like so:

I put the same command: gem inst jekyll, but the results are same. Thanks for help anyway! I think I should read the manual carefully and try again...

[larskanis]

Could it be that the username you're using consists of an invalid byte sequence? The error message looks like that. You might try an ASCII only name instead.

[mohits]

@larskanis - I wonder if this is related to this earlier issue: #265

[kubo]

@yunkyukim Could you post command output as @larskanis requested at #320 (comment)? Copy whole command output, not only the error lines, and paste it in a code block. The location of the error may be a hint to resolve this.

By the way, it may be fixed by changing TMP and TEMP environment variables as follows. The default value of them is C:\Users\%USERNAME%\AppData\Local\Temp and cc4K9XbU.s looks a temporary file created in the temporary directory specified by TMP or TEMP. I guess that it is fixed when either TMP or TEMP doesn't contain non-ASCII characters.

mkdir c:\temp
set TMP=c:\temp
set TEMP=c:\temp
gem inst jekyll --no-doc

[yunkyukim]

@kubo My username is in Korean so I guess it is the reason.
Here's the whole command:

@yunkyukim
Could you create a directory c:\temp and set TMP=c:\temp as described in #320 (comment)?

I reproduced this issue by setting TMP=c:\いろは on Japanese version of Windows as follows. I guess that this can be reproduced by setting a non-ASCII path to TMP on other language versions.

C:\ruby\rubyinstaller-3.1.0-1-x64\bin>mkdir c:\いろは

Thank you @kubo ! I can reproduce the issue as well by setting TMP to a unicode path. The issue is in gcc which seems to not use Unicode WINAPI. One can work around by setting the gcc options like so:

I wonder if we should enable these options by default in RubyInstaller. -pipe is save to be used on Windows and fixes the issue for *.c files when invoking the assembler. -pipe is already enabled for *.cpp. So this is a no-brainer. I'm uncertain if -save-temps could have a negative impact. Any idea?

[kubo]

This is just information. I'm not against the fix.

In aa15f1a

cmd and powershell mechanism to set variables doesn't support Unicode either.

cmd in Japanese version of Windows supports Unicode characters as long as they are in CP932 (ANSI and OEM code page in Japanese version). I bet that c:\いろは in Japanese version and C:\Users\나\AppData\Local\Temp in Korean version cause no problems if gcc uses ANSI API in all places and treats byte sequence got by ANSI API as it is. The problem is that gcc supports unicode partly and decodes byte sequence of ANSI code page as UTF-8.

In order to check it, I set TMP=c:\ﾂｱ on Japanese version and got the error message: "No such file or directory" instead of "Illegal byte sequence".

Error: can't open c:\±\ccKrzIwR.s for reading: No such file or directory

The byte sequence of c:\ﾂｱ in CP932 is 63 3A 5C C2 B1, which is also legal byte sequence of c:\± in UTF-8. So the error message "Illegal byte sequence" disappears.

character	byte sequence in cp932	byte sequence in utf-8
c	63	63
:	3A	3A
\	5C	5C
ﾂ	C2	EF BE 82
ｱ	B1	EF BD B1
±	81 7D	C2 B1
