Build instructions for EasyHttp Release 2.x.x?
Brief overview
I tried to build EasyHttp on Windows using the wiki guide. It worked for EasyHttp 1.0.0, but not for 2.0.0 or 2.1.0.
First I was getting this error:
CMake Error at C:/repo/poco/NetSSL_Win/cmake/PocoNetSSLWinConfig.cmake:5 (include):
include could not find load file:
C:/repo/poco/NetSSL_Win/cmake/PocoNetSSLWinTargets.cmake
I fixed it by changing my Poco CMake command to this:
cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_NETSSL_WIN=ON ../
But now I have a new issue when I try to build:
C:\repo\easyhttpcpp\_build>cmake -DCMAKE_PREFIX_PATH="C:/repo/poco/_build" ..

What am I doing wrong?
Steps to reproduce
-
Get a Windows 10 x64 machine.
-
Check out release 2.1.0.
-
Follow wiki guide.
-
(Optional) Get rid of first error by replacing poco cmake command with
cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_NETSSL_WIN=ON ../.
Specifications like the version of the project, operating system, or hardware etc.
Poco 1.7.9.
Windows 10 x64 on a Dell G3 laptop.
Hi @serg06
I am sorry for not updating the Wiki after 2.x.x release.
For building EasyHttp 2.x.x on Windows, here are the steps (will update Wiki once this issue is fixed):
- Install Poco:
When installing Poco, please make sure to use the following settings (especially note this part -DENABLE_NET=ON -DENABLE_NETSSL=OFF -DENABLE_NETSSL_WIN=ON -DENABLE_CRYPTO=OFF)
Please change %PATH_TO_INSTALL_FOLDER%
C:\> cmake -G "Visual Studio %CMAKE_VS_VERSION%" -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_STANDARD=11 -DCMAKE_CXX_STANDARD_REQUIRED=ON -DPOCO_VERBOSE_MESSAGES=OFF -DPOCO_STATIC=ON -DPOCO_UNBUNDLED=OFF -DENABLE_XML=ON -DENABLE_JSON=ON -DENABLE_UTIL=ON -DENABLE_NET=ON -DENABLE_NETSSL=OFF -DENABLE_NETSSL_WIN=ON -DENABLE_CRYPTO=OFF -DENABLE_DATA=ON -DENABLE_DATA_SQLITE=ON -DENABLE_ZIP=OFF -DENABLE_DATA_MYSQL=OFF -DENABLE_DATA_ODBC=OFF -DENABLE_MONGODB=OFF -DENABLE_PDF=OFF -DENABLE_SEVENZIP=OFF -DENABLE_PAGECOMPILER=OFF -DENABLE_PAGECOMPILER_FILE2PAGE=OFF -DENABLE_TESTS=OFF -DCMAKE_INSTALL_PREFIX="%PATH_TO_INSTALL_FOLDER%" ../
C:\> "C:/Program Files (x86)/MSBuild/14.0/Bin/MSBuild.exe" Poco.sln
C:\> "C:/Program Files (x86)/MSBuild/14.0/Bin/MSBuild.exe" INSTALL.vcxproj
- Use installed Poco when building EasyHttp:
Please change
%PATH_TO_INSTALL_FOLDER%
C:\> cmake -G "Visual Studio %CMAKE_VS_VERSION%" -DCMAKE_BUILD_TYPE=Release -DEASYHTTPCPP_VERBOSE_MESSAGES=ON -DCMAKE_CXX_STANDARD=11 -DCMAKE_CXX_STANDARD_REQUIRED=ON -DCMAKE_PREFIX_PATH="%PATH_TO_INSTALL_FOLDER%" -DENABLE_TESTS=ON -DCMAKE_INSTALL_PREFIX="%PATH_TO_INSTALL_FOLDER%" ../
C:\> "C:/Program Files (x86)/MSBuild/14.0/Bin/MSBuild.exe" easyhttpcpp.sln
C:\> "C:/Program Files (x86)/MSBuild/14.0/Bin/MSBuild.exe" INSTALL.vcxproj
Let me know if this works.
Hi @shekharhimanshu, thanks for the reply.
I tried building Poco 1.7.9 and EasyHttpCpp 2.1.0 with those commands. All the Poco steps worked perfectly, but the EasyHttpCpp cmake step failed.
Here's the command, with %PATH_TO_INSTALL_FOLDER% replaced with the same value as I used in the Poco cmake command:
cmake -DCMAKE_BUILD_TYPE=Release -DEASYHTTPCPP_VERBOSE_MESSAGES=ON -DCMAKE_CXX_STANDARD=11 -DCMAKE_CXX_STANDARD_REQUIRED=ON -DCMAKE_PREFIX_PATH="C:/lib/easyhttpcpp" -DENABLE_TESTS=ON -DCMAKE_INSTALL_PREFIX="C:/lib/easyhttpcpp" ../
And the error:
-- Building static easyhttpcpp libraries
CMake Error at tests/CMakeLists.txt:7 (find_package):
Could not find a package configuration file provided by "GMock" with any of
the following names:
GMockConfig.cmake
gmock-config.cmake
Add the installation prefix of "GMock" to CMAKE_PREFIX_PATH or set
"GMock_DIR" to a directory containing one of the above files. If "GMock"
provides a separate development package or SDK, be sure it has been
installed.
-- Configuring incomplete, errors occurred!
My bad. Sorry about that.
We need googletest for testing purposes.
In step 2, kindly turn off tests, -DENABLE_TESTS=ON -> -DENABLE_TESTS=OFF.
- Use installed Poco when building EasyHttp:
Please change
%PATH_TO_INSTALL_FOLDER%
C:\> cmake -G "Visual Studio %CMAKE_VS_VERSION%" -DCMAKE_BUILD_TYPE=Release -DEASYHTTPCPP_VERBOSE_MESSAGES=ON -DCMAKE_CXX_STANDARD=11 -DCMAKE_CXX_STANDARD_REQUIRED=ON -DCMAKE_PREFIX_PATH="%PATH_TO_INSTALL_FOLDER%" -DENABLE_TESTS=OFF -DCMAKE_INSTALL_PREFIX="%PATH_TO_INSTALL_FOLDER%" ../
C:\> "C:/Program Files (x86)/MSBuild/14.0/Bin/MSBuild.exe" easyhttpcpp.sln
C:\> "C:/Program Files (x86)/MSBuild/14.0/Bin/MSBuild.exe" INSTALL.vcxproj
If you wish to build EasyHttp tests as well, please install GoogleTest as well. Let me know if this works.
