C compilation error

[anders]

Hi

I am compiling a project with 15.08 and I get this error:

big_file_C1_c.c

C:\EiffelStudio1508GPL\library\cURL\spec\include\curl/curl.h(176) : error C2061: syntax error : identifier 'curl_socket_t'

Is it that I am using an old compiler or any idea of what the cause could be?

It compiles find at another computer.

Installation information:

Version = EiffelStudio 15 (15.08.9.7862 GPL Edition - win64)

$ISE_EIFFEL = C:\EiffelStudio1508GPL

$ISE_LIBRARY = C:\EiffelStudio1508GPL

$ISE_PLATFORM = win64

$ISE_C_COMPILER = msc

Hi,

It is likely to be an issue between  Eiffel libCurl and Eiffel Net (SSL) on Windows.

I guess you are using libcurl, but are you using also Eiffel Net SSL or Eiffel zeromq wrapper?

We noticed such issue. And no obvious solution.

It is a conflict related to the versions of winsock included in the project.

As part of a solution, the EiffelWeb framework team we have been working on providing a new implementation of the http_client, which is based on EiffelNET (SSL).

It is not yet integrated, but recent tests are encouraging. So this would be a solution to workaround conflict when using libcurl and Net SSL at the same time.

We should be able to provide this new "simple" http_client implementation probably next week (it has a few limitations but should not matter for general usage)

Apart from this workaround, if anyone knows a solution for the winsock conflict between libcurl and openssl for instance, please let us know.

Regards,

-- Jocelyn

I am using libcorl and zeromq

Yes I rememberd it but I forgott about it due to that I was able to build it at another computer with Windows 8.1. I will invetigate if I can find a reason for the difference, e.g. why it builds at my Windows 8.1 computer.

Ok, I can test it later when available. Not an urgent task for me at the moment.

Hi

I removed zeromq from my build and then tried again but the I got link problems. Do you recognize what could cause this problem. I got about 1300 errors like this. I did a "clean" of EIFGEN before building.

Hi Anders, 

Can you verify the Microsoft C++ compiler are you using?

From command line type cl.

/Javier

[Emmanuel Stapf]

I think the issue is that some part of the C code was compiled with a 32-bit C compiler whereas you are using the 64-bit version of EiffelStudio.

 

I would delete the .obj and .lib files where you have the error and relaunch the C compilation from EiffelStudio.

 

Regards,

Manu

Hi

I should probably use a 32 bit version of Eiffel Studio at that computer since it is Windows Vista running at it and I can not install the community edition of MS VS 2012 at that, e.g. I get a message that says that it is not supporting that operating systems. I have been using VS version 10.0 so far with older version of Eiffel Studio.

Hi I have this C-compilers

EiffelStudio is ready to be used for the win64 platform and msc C compiler.
