Does infer support Makefile generated by CMake? about infer

[yagamy4680]

Here is a simpler way to reproduce this issue:

main.c

#include <stdio.h>

int main()
{
    int *s = NULL;
    *s = 42;
    printf("hello world. \n");
}

CMakeLists.txt

cmake_minimum_required (VERSION 2.6)

project(ex1)
add_executable(ex1 main.c)

Using makefile generated by CMake:

# cmake .
# make clean
# infer -- make

Scanning dependencies of target ex1
[100%] Building C object CMakeFiles/ex1.dir/main.c.o
Linking C executable ex1
[100%] Built target ex1

Compile main.c with gcc and infer:

# infer -- gcc ./main.c

1 file analyzed


main.c:6: error: NULL_DEREFERENCE
   pointer s last assigned on line 5 could be null and is dereferenced at line 6, column 5

The problem is that cmake generates a Makefile which runs directly /usr/bin/cc, so infer cannot replace it by its own wrapper (since it relies on ugly $PATH tricks).

It works if you explicitly change the CC variable in order to use the infer wrapper:

CC=/path/to/infer/infer/lib/capture/clang cmake .
infer -- make

Be careful that CC can be set only one time, so you will need to clean all the cmake cache files or to use a fresh out-of-sources build directory.

Thanks, it works.

infer 0.8.0 from Homebrew doesn't appear to have a path like .../lib/capture/clang. Is there a similar command for running infer 0.8.0 against cmake-generated Makefiles?

The new way is easier: just run infer -- cmake ....

I forgot to comment again on this issue when I pushed 9f10b09 😶

@jvillard I tried using infer -- cmake . for exiv2, but it seems that the wrapper fails to detect some dependency library:

CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find ZLIB (missing: ZLIB_LIBRARY) (found version "1.2.11")
Call Stack (most recent call first):
  /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)

  cmake/findDependencies.cmake:22 (find_package)
  CMakeLists.txt:63 (include)

While the library can be correctly found by cmake . even when I export CC=/path/to/infer/clang/wrapper:

-- Found Threads: TRUE
-- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version "1.2.11")

-- Found Iconv: /usr/lib/x86_64-linux-gnu/libc.so
-- ICONV_INCLUDE_DIR :
-- ICONV_LIBRARIES : /usr/lib/x86_64-linux-gnu/libc.so

On the other hand, export CC=/path/to/infer/clang/wrapper followed by infer -- make emits similar messages like There was nothing to analyze..

May I know the possible reasons?
