dotnet-r2pipe on Mono 3.12 using radare2 0.9.9-git aka radare-0.9.8-813.g37cfb20 commit 7161 works fine and as expected.

The same code under Windows however doesn't run. radare2 0.9.9-git aka jenkins-radare2-w32-4239 commit 7779 just hangs and uses somewhere between 10 and 20% CPU constantly.

Tested with both master dotnet-r2pipe and my reworked fork. Same behavior.

• Use let and const where possible.
• Arrow functions in examples
• Support coroutines with generators and such (future premises)

E.g. to build ocaml bindings - we need to run

./configure --enable=ocaml
make
make install

Only Perl 5.10 is supported right now since /usr/lib/perl/5.10/CORE is set in the Makefile. The quick fix is to ask perl itself where to find archlib:

-       -${CC} ${CFLAGS} -I/usr/lib/perl/5.10/CORE/ \
+       -${CC} ${CFLAGS} -I$(shell perl -MConfig -e 'print $$Config{archlib}')/CORE/ \

When I use this little script I have an corrupted double-linked list.
If I replace /bin/true by /bin/ls I have a segfault.

from r2 import r_core

rc = r_core.RCore()

rc.file_open("/bin/true", 0, 0)

rc.bin_load("", 0)

rc.anal_all()

rc.anal.get_fcns()[0].get_bbs()

cc @crowell

use anal->reg

    R_ANAL_DATA_TYPE_REGISTER = 10

in theory this command should be used to analyze the conetns of the memory. not the offsets of it. so this feature must identify numeric values that are referenced by any register.

Hi,

I am currently trying to use the Java version of the API to get all of the strings from a binary file. However, it seems that radare does not know automatically what file type the file is, so it doesn't return anything when I load the file up into an RBin object and try to use the get_strings() method. This also makes sense because when I try to analyze the file with rabin2 via command line to get the strings it gives me the warning:

WARN: Use '-e bin.rawstr=true' or 'rabin2 -zz' to find strings on unknown file types

So then when I try again with the -zz flag, it finds all of the strings.

I was wondering if there is a way to find all of the strings in an unknown file type from the API? I have already tried using RCore but I believe that passing commands via RCore is only for commands from within Radare and not other commands like rabin2?

If anyone has any ideas that would be great!

Thanks,

• Fix Python Ctypes binding
• Fix Node.JS bindings (requires changes to the valabind - nodejs ffi interface)

Radare2 is not outputting JSON, but things like:

[{u'type': u'C', u'from': 4269326, u'opcode': u'call section..init'}]

Notice the u prefix; meaning that it's unicode.

When radare2 is not installed in the default /usr (e.g. ~/radare) then pkg-config does not find cflags for r_core, r_util, etc.

A simple work-around for cflags is to define PKG_CONFIG_PATH=${RADARE}/lib/pkgconfig where $RADARE points to the radare2 installation directory. Maybe configure should have a flag --with-radare=DIR and then define PKG_CONFIG_PATH accordingly in all Makefiles.

This same issue makes building of language bindings in libr/lang/p fail since LDFLAGS lacks the path to radare2 lib directory. Once, pkg-config can find r_core, it can be easily solved replacing:

-LDFLAGS_LIB=-lr_core -lr_util -shared
+LDFLAGS_LIB=$(shell pkg-config --libs-only-L r_core) -lr_core -lr_util -shared

Hi,

By default, ruby bindings are getting installed into /usr/lib instead of /usr/lib64 (64bit system)

/usr/lib64/python2.7/site-packages/r2/r_core.py
/usr/lib/ruby/1.9.1/r2/test-r_core.rb

I'm compiling the software in a strict environment and it prevents me from installing ruby bindings
For more details, see the following document: https://devmanual.gentoo.org/archs/amd64/

Getting this from valgrind using the C pipe, which is using r_socket.h and r2pipe.c.

Why is this a problem?

I'm not sure if this is the appropriate place for this issue, however I'm getting inconsistent results when using the Ruby r2pipe gem vs Radare2.

For reference, the binary that I'm looking at is MD5: 5896d840a314e8bc86ceadb5a6450cf8

When using Radare2, I'm able to see the full list of functions, below is a snippet

:~> radare2 -A  5896d840a314e8bc86ceadb5a6450cf8

When using the Ruby API, the following information is returned

:~> irb

irb(main):002:0> r2p = R2Pipe.new("5896d840a314e8bc86ceadb5a6450cf8")

=> "1\r\n"
irb(main):005:0> r2p.cmd('afl')
=> "0x0040508e  235  6  entry0\r\n"

Is there a reason that r2pipe is only seeing 1 function listed versus the 152 recognized by Radare2?

Thank you for your time.

Some linker flags are missing. I'll submit a pull request.

Then we will add CI job for radare2-ctypes-tests

A simple script like the one below will grab CTRL-C in the bin_load() call so that script dont get the interrupt.

from r2 import r_core
rc = r_core.RCore()
rc.file_open("/bin/ls", 0, 0)
rc.bin_load("/bin/ls", 0)
raw_input()

Try control-c when waiting for user input to verify

I am unable to get the Go-language bindings working with r2. I don't think this is due to an issue with r2 being in a state of flux, rather I think it has something to do with the binding generation themselves. I fixed as many Go binding bugs as I could (see other PRs), but I'm woefully uneducated in SWIG.

Details:

$ cd radare2-bindings/go
$ # remove Makefile line 5 (`include ../rules.mk`), as described in #26, or we don't get anywhere
$ make r_bin.so
  ...   # output looks fine

  void _wrap_RListIter_get_next(void *swig_v) { RListIter *arg1 = (RListIter *) 0 ;     RListIter *result = 0 ; struct swigargs {

I think the fix would be small, but requires insight into r2 and SWIG (which I don't have yet). If you could dedicate a little time to fixing the the issue, I'd really appreciate it. Otherwise, if you could point me towards the appropriate resources to learn to do it myself, that would be a great help.

Hi,

I tried to build the Python bindings but I'm having problems:

$ ./configure --enable=python
(...stripped...)
$ make
make -C libr/lang/p
make[1]: *** No hay ninguna regla para construir el objetivo «lang_tcc.so», necesario para «all».  Alto.
make: *** [all] Error 2

Any idea?

We need some extra options for r2pipe:

• path to r2 binary (actually is 'radare2' in $PATH)
• extra commandline options for spawn/launch

Subj,

Trying to do make install when having several lua versions installed seems to break the code inside Makefile. The problem seems to be that LUAPKG and LUADIR point to both versions and both paths so the cp command ends being malformed.

Improve building system to be able run ./configure with --select-python, --select-ruby, etc, then make, then make install. Now it is completely independent codebase, so can be simplified in this way. Also, it is possible to define languages to be built at once, and you'll get both bindings and lang_* plugin for chosen language.

For rlang and local-pipe. Not sure about json, http/tcp if we should use an async lib, etc.

I compiled the Java Bindings on Ubuntu 13.10 and some objects (RAsm, RFSFile, RAsmOp, RAnal, RMeta) give me a java.lang.UnsatisfiedLinkError when I try to call the constructors for them, while other objects (RBin) are constructed fine. The example .java file that comes with the bindings runs fine because it only uses a RBin object, RBinSection object, and RBinSectionVector object but all of the other objects I have tried to create so far have not worked.

Is anyone else having this same problem? Any ideas for how I might be able to fix this?

Thanks,
