Update PHP module docs

[mandito67]

Hello!

I'm trying to install PHP wrapper on linux server. In the installation instructions from this site: http://www.coolprop.org/coolprop/wrappers/PHP/index.html says to create de module with
cmake .. -DCOOLPROP_PHP_MODULE=ON but it returns two errors on line 830 and 831. Somewhere on the net I found to add "" to the variable ${php_config_includes} in both lines and this returns no errors, but when building with make VERBOSE=1 it cant find the CoolProp/build/src folder

please any suggestion??

[ibell]

Please provide a complete build log so we can debug

This is the code on the CMakeLists.txt where variables have to be quoted for returning no errors.

if (COOLPROP_PHP_MODULE)

Must have SWIG

FIND_PACKAGE(SWIG REQUIRED)
INCLUDE(${SWIG_USE_FILE})

execute_process(
COMMAND php-config --includes
OUTPUT_VARIABLE php_config_includes
RESULT_VARIABLE php_config_failed
)
string(STRIP "${php_config_includes}" php_config_includes)
string(REPLACE "-I" "" PHP_INCLUDES "${php_config_includes}")
SEPARATE_ARGUMENTS(PHP_INCLUDES)

message(STATUS "php includes=${PHP_INCLUDES}")
include_directories(${PHP_INCLUDES})

add_definitions(-DNO_ERROR_CATCHING) #disable internal error catching and allow swig to do the error catching itself

set(I_FILE "${CMAKE_CURRENT_SOURCE_DIR}/src/CoolProp.i")

set(SWIG_OPTIONS "${COOLPROP_SWIG_OPTIONS}")
string(REPLACE " " ";" SWIG_OPTIONS "${SWIG_OPTIONS}")
SET_SOURCE_FILES_PROPERTIES(${I_FILE} PROPERTIES SWIG_FLAGS "${SWIG_OPTIONS}")
SET_SOURCE_FILES_PROPERTIES(${I_FILE} PROPERTIES CPLUSPLUS ON)

SET(SWIG_MODULE_CoolProp_EXTRA_DEPS ${SWIG_DEPENDENCIES})
SWIG_ADD_MODULE(CoolProp php ${I_FILE} ${APP_SOURCES})

if (WIN32)
set_target_properties(CoolProp PROPERTIES PREFIX "")
endif()

if (NOT MSVC)
set_target_properties(CoolProp PROPERTIES COMPILE_FLAGS "-m${BITNESS}" LINK_FLAGS "-m${BITNESS}")
endif()
add_dependencies (CoolProp generate_headers)

install (FILES ${CMAKE_CURRENT_BINARY_DIR}/CoolProp.php DESTINATION ${CMAKE_INSTALL_PREFIX}/PHP/cross-platform)
install (TARGETS ${app_name} DESTINATION ${CMAKE_INSTALL_PREFIX}/PHP/${CMAKE_SYSTEM_NAME})

endif()

That push should have fixed the quote escaping, can you please provide a full build log of your attempts to build PHP wrapper? It works on our build server... http://www.coolprop.dreamhosters.com:8010/builders/PHP-linux/builds/1599

[mandito67]

for background, I'm working on a AWS Linux instance. I connect to the vm with cmd and cygwin plugins. This is teh error I get when trying:

[ec2-user@ip-xx-xx-xx-xx build]$ cmake .. -DCOOLPROP_PHP_MODULE=ON
-- COOLPROP_INSTALL_PREFIX=/home/ec2-user/CoolProp/install_root
-- CoolProp version: 6.0.1dev
CMake Error at CakeLists.txt:830 (string):

CMake Error at CakeLists.txt:831 (string):

-- php includes=
-- Configuring incomplete, errors ocurred!
See also "/home/ec2-user/CoolProp/build/CMakeFiles/CMakeOutput.log".

[ibell]

Did you pull the updated CMakeLists.txt? Hopefully that error should be fixed with my commit: cf74ce3

[ibell]

Also, make sure you pull the submodules again.

[mandito67]

Hello Ian, I've been asking around and somebody told me maybe it is related to the Linux version I'm using. I'm working with Amazon Linux AMI instance on AWS/EC2. What Linux do you use to check it out??

[ibell]

1. Did you do a git pull to update CMakeLists.txt?
2. I use xubuntu, and you should definitely test it all on your computer before you try on AWS

A full build log could be useful!

Can you please provide the full command line output, showing all the commands you ran and the associated output? A copy-paste from the terminal would be perfect.

I'd like to see a similar log for you.

[ibell]

I updated the docs too: http://www.coolprop.org/dev/coolprop/wrappers/PHP/index.html#php (might need to wait a while for them)

[ibell]

Closing, reopen if it doesn't work for you.

Now I need to do some tests on php...let you know! thanks!!

[ibell]

Good to hear!

[ibell]

In the future, please provide THE WHOLE build log, including the commands that you ran. Otherwise I need to guess what you actually did.

[mandito67]

Sorry for that, I'm new on this, trying to catch up :)

error coolprop.txt
Ian, sorry for bother. Please check last 5 lines.

[mandito67]

Ian, working!! thanks a lot.
In the documentation website I think you have to change extension = "CoolProp.so" for libCoolProp.so
Thanks what I did and it works.
