Baseline incorrect with Chinese characters

[mgieseki]

Could you please provide the font 华文仿宋 or post a link where it can be downloaded? Currently, I can't test your example because of the missing font.
If possible, also try to convert your file with the latest version 3.1.2 of dvisvgm and check whether the issue occurs there as well.

[mgieseki]

The issue might be the same as #235 which has been fixed in dvisvgm 3.1.

[archcst]

Thanks for your fast response.
Is there anyway upgrade dvisvgm via Hombrew?

[mgieseki]

Unfortunately, I don't know since I'm not familiar with Homebrew. Maybe you could ask on their discussion page if they provide a more recent version.

[archcst]

I’ll try to compile the latest version, you may close this one, thanks again

Ok, thanks for the update. Please let me know if the latest version fixes the problem for you. Otherwise, I'll have a look what's actually going on.

Hi, I'm encountering a compile issue with the 3.1.2 release. Could you please help on this?

Undefined symbols for architecture arm64:
  "_main", referenced from:
     implicit entry/start for main executable
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [hashcheck] Error 1
make[2]: *** [check-am] Error 2
make[1]: *** [check-recursive] Error 1
make: *** [check-recursive] Error 1

[mgieseki]

Could you please attach the entire build log including the output of configure and make? The single linker error message doesn't provide enough information to determine the cause of the failure.

Please find log in the attachment, tks

The dvisvgm binary seems to be built correctly and should be located in the src directory. However, the test hashcheck can't be built, probably because the corresponding source file hashcheck.cpp wasn't created correctly. Maybe it's empty on your system.
The file should be created during the build process by genhashcheck.py which requires Python and the Python package xxhash to be installed.
You can try to build it manually by calling make hashcheck inside directory tests. Afterwards have a look at the file and check if the main function is present there. If not, some Python stuff is probably missing on your computer.

[archcst]

You remind me when I compile dvisvgm it hints couldn’t find `python` command (the built in python command in Mac is `python3`), therefore I add an shell alias pointing `python` to `python3` for working around. Is it the right way to do so?

Yes, that should work. On Linux, python is usually a symbolic link to the python3 executable:

> ls -la /usr/bin/python
lrwxrwxrwx. 1 root root 9  3. Okt 02:00 /usr/bin/python -> ./python3

[archcst]

I found the dvisvgm file and mv it to /usr/local/bin, now it works fine with 3.12 version, thanks a lot!

but I get this message,

❯  dvisvgm --version

It's wired I'm pretty sure I have installed Ghostscript

❯  brew list | grep ghostscript
ghostscript

Any hints?

[mgieseki]

Great to hear that the latest version fixes the issue for you.

It's wired I'm pretty sure I have installed Ghostscript

dvisvgm requires the Ghostscript library, the Ghostscript executable is not sufficient. You need to make sure that the library is accessible through the search path of the dynamic linker or specify the path with option --libgs or environment variable LIBGS. Since I don't know much about MacOs, I can't give more specific hints. Here you'll find some more information:

Thanks a lot, all problem solved!
