Build error on Android (Termux): unknown type name 'ulong'

[aureliojargas]

Just did a git clone now and tried to compile the master branch in my Android phone, via the Termux app, which is a nice Linux environment.

This is the log until the first error:

$ make
Scanning dependencies of target tidy-share

            ^

I don't have C/C++ programing experience, but I've found tips online and managed to successfully build tidy by just adding the following line to the top of src/config.h and include/tidy.h:

typedef unsigned long ulong;

I guess this is not the proper fix, but I'm happy to provide a pull request if somebody can point me to the right direction. I can also do more tests in my phone if necessary.

I really want upstream tidy building in my phone without my little hack :)

I'd try adding your OS to the list at
https://github.com/htacg/tidy-html5/blob/next/include/tidyplatform.h#L572

#if defined(HPUX_OS) || defined(CYGWIN_OS) ..snip..
#  undef ulong
   typedef unsigned long ulong;
#endif

@aureliojargas wow, that sounds fun - compile tidy in an Android phone, using the Termux app... must see if I can find the time to do that... but would need lots of help...

As @ler762 points out, if you can find what gcc defines we can add it to the list in tidyplatform.h, and make it permanent for future users...

To find the list of gcc predefines you should be able to run $ gcc -dM -E - < /dev/null...

Unfortunately, this can be a long list, and it is hard to choose the correct define...

The closest I can come to such a restricted environment is my RPI2 list...

There tidy compiles, no problem, so it defines something agreeable in tidyplatform.h ...

I could guess at #elif defined(linux) || defined(__linux__) failing, since I hope Termux at least defines linux, else all bets are off...

This could be a difficult search, but hope some feedback can provide permanent resolution... thanks...

Hi @geoffmcl and @ler762, thanks for all the information!

I'm not sure I understood 100%, but here is the command output, run inside Termux:

Just add || defined(__ANDROID__) on line 572 of tidyplatform.h

[naveedpash]

#823 @ler762

[geoffmcl]

@naveedpash @ler762 @da2x et al... sorry for the delay...

[aureliojargas]

Great! I confirm that this is working fine.

git clone git@github.com:htacg/tidy-html5.git
cd tidy-html5/build/cmake/
cmake ../.. -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIB:BOOL=OFF
make

The compilation when on without errors and produced the expected working binary:

$ ./tidy --version
HTML Tidy for Linux version 5.7.27
$

Thank you! 🎉
