Can't use Latexmk

[RobertAudi]

When I use :Latexmk I get the following error:

Compiling to pdf ... (async off!)
Error detected while processing function LatexBox_Latexmk..LatexBox_LatexErrors:
line   16:
E40: Can't open errorfile /Users/aziz/Documents/LateX/test.log
Error detected while processing function LatexBox_Latexmk:
line  152:
E171: Missing :endif
Press ENTER or type command to continue

By adding this line to my .vimrc I solved the problem:

let g:LatexBox_latexmk_async=1

Sorry about that...

[lervag]

No problem!

I have this too, but don't want to use Vim Server, so Aziz' solution does not work.

Do you have any idea?

[lervag]

First: What version of vim are you using?
Second: What are your LaTeX-Box settings (in vimrc)?
Third: Are you using the latest version of LaTeX-Box?

1. inbuilt VIM, OS X mavericks, but I get the same error with MacVim installed with Homebrew
2. Commented them all out.
3. Yes, I am at the latest commit

Ok. Next step: Does the file compile at all? If so, what is the path of the log file? As you see from the error message, vim does not find the log file, so the bug might simply be that the path is incorrect.

[y0ast]

It does not compile at all, no log or pdf files are generated. If I run pdflatex on the file manually in the terminal it works fine and the pdf output is good.

Ok. I am unfortunately not able to reproduce your problem, which makes it difficult to debug. I can try to assist in finding a solution, though.

I think the error may be related to line 290 in the file latexmk.vim. If you could change

echo 'Compiling to ' . g:LatexBox_output_type . ' ... (async off!)'
call system(cmd)
call LatexBox_LatexErrors(v:shell_error)

to

echo 'Compiling to ' . g:LatexBox_output_type . ' ... (async off!)'
echom cmd
call system(cmd)
echom v:shell_error
call LatexBox_LatexErrors(v:shell_error)

And report the output here. One possible solution is to change the system command:

echo 'Compiling to ' . g:LatexBox_output_type . ' ... (async off!)'
execute cmd
call LatexBox_LatexErrors(v:shell_error)

[y0ast]

I changed the file as you described, here is the output:

Compiling to pdf ... (async off!)
cd '/Users/joost' && max_print_line=2000   latexmk -pdf -quiet  -e '$pdflatex =~ s/ / -file-line-e
rror /' -e '$latex =~ s/ / -file-line-error /' hw1.tex &>/dev/null

Error detected while processing function LatexBox_Latexmk..LatexBox_LatexErrors:
line   16:
E40: Can't open errorfile /Users/joost/hw1.log
Error detected while processing function LatexBox_Latexmk:
line  154:
E171: Missing :endif

It seems like the command is never properly executed and then latex-box fails upon trying to open the non-existing log file.

Your possible solution does not fix it, generates exact same error as before.

Running:
pdflatex hw1.tex

Produces:
hw1.aux hw1.log hw1.pdf hw1.tex

Strange. Could you try to comment out line 190 (remove &>/dev/null) and use the execute form. I think this should lead to more verbose output, which might help explain what is happening.

Oh, I forgot: When you change from call system(... to execute cmd, you must add ! to the beginning of the command. That is, add

let cmd = '!' . cmd

before execute cmd.

If this doesn't work, you can also try to run the command yourself directly. Copy the command to you commandline, remember to prepend with !, and run the command.

[y0ast]

Ah, that gave the output that latexmk is not found.

I downloaded the BasicTex package from MacTex to save harddrive space (128GB SSD fills up quickly) and apparently that doesn't come with latexmk. Manually installing it from here: http://users.phys.psu.edu/~collins/software/latexmk-jcc/ solved it :)

Thanks for your help! Maybe you could implement a more helpful error message in this case.

[lervag]

No problem, happy to help.

Yes, you are right, we should have a better error message for this case. I would be happy to do so, but I don't have time right now. Could you open a new issue for this (I don't want to reopen this particular issue)?
