Error when installing r2api-python

[raulsiles]

Following the r2 installation instructions at https://github.com/radare/radare2, r2 properly installs for the user (not system-wide) in macOS High Sierra:

$ git clone https://github.com/radare/radare2.git
$ cd radare2
$ sys/user.sh

Then, after successfully initializing the package manager with r2pm init, I proceed to install the Python bindings:

$ r2pm install lang-python2
$ r2pm install r2api-python
...
==> Using valabind 1.4
==> Using swig 3.0.12
...

The first command completed successfully, but the second one generates the following errors:

r_core_wrap.cxx:7410:10: error: no matching function for call to 'r_core_asm_strsearch'
                list = r_core_asm_strsearch (self, input, from, to, maxhits, regexp);

BTW, I started with a make purge to clean up potential files from previous r2 versions. Python version is 2.7.13.

[radare]

pls confirm its fixed

[radare]

if not check the last commit and send a pr adjusting the vapi files

After the last commit https://github.com/radare/radare2-bindings/blob/da5fa8df7dd99a460ebe383c175d4449908a1676/vapi/r_core.vapi the "r_core_asm_strsearch" error has been fixed, but the "r_meta_del" error still remains:

I have submitted a PR for "vapi/r_anal.vapi" that fixes that second error too: https://github.com/radare/radare2-bindings/pull/178

Thanks for the reference and guidance!

Cool thanks!

Those bindings are not recommended to be used because they leak, crash and are not complete. We need more human power to maintain those and actually the r2pipe is easier to use and maintain

Thanks anyway :)
