I am trying to build DocFormats in Cloud9 and the make command fails with C99
mode in for loops. I have verified that CMakeList.txt file contains -std=c99 in
this if block
if(${CMAKE_SYSTEM_NAME} MATCHES "Linux")
set(CMAKE_C_FLAGS "-std=c99 -D_GNU_SOURCE -g")
set(LIBS ${LIBS} m pthread xml2 z SDL2 SDL2_image)
endif(${CMAKE_SYSTEM_NAME} MATCHES "Linux")
I am doing this:
git clone https://git-wip-us.apache.org/repos/asf/incubator-corinthia.git
incubator-corinthia
cd incubator-corinthia/
sudo apt-get install -y cmake
mkdir build
cd build/
export DOCFORMATS_DIR=../DocFormats/
cmake -G "Unix Makefiles" $DOCFORMATS_DIR
make
Below you can see the commands that I have executed and their outputs

Any idea how to fix it?
