develop branch does not build

[zhulika]

Expected behavior

msbuildwin to work

Actual behavior

it fails at the MySQL stage with:

`++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++ Building [MySQL_vs150.vcxproj] ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

msbuild /clp:NoSummary /nologo /v:minimal /p:UseEnv=true /m /t:build /p:Configuration=debug_shared /p:Platform=Win32 MySQL_vs150.vcxproj Utility.cpp c:\program files\mysql\mysql server 8.0\include\mysql\client_plugin.h(108): error C2371: 'MYSQL': redefinition; differe nt basic types [D:\work\github\poco\SQL\MySQL\MySQL_vs150.vcxproj] d:\work\github\poco\sql\mysql\include\poco\sql\mysql\utility.h(26): note: see declaration of 'MYSQL' d`

Steps to reproduce the problem

(please make this a SSCCE, if applicable and reasonable)

1. git clone this repo
2. delete openssl folder and "git clone https://github.com/pocoproject/openssl"
3. install MySql and set the INCLUDE / LIB evars
4. run "buildwin 150 build all both Win32"

POCO version

git commit 45903ed071df1becb26bae9add6cb9cbd3e460e6

Compiler and version

Microsoft Visual Studio 2017

Operating system and version

Windows 10

Other relevant information

I restarted buildwin at least once, because I failed to install OpenSSL correctly the first time. Does it cope with being restarted after I fix each problem (I'm too lazy to try to get everything right first time!)

you need mysql client headers and libraries in order to build mysql. this is the case for any external dependency (mysql, postgresql, openssl)

[zhulika]

I'm a bit confused, though this may be because I am not familiar enough with what you are saying.

Is the error message not coming from the duplicate definition that the compiler is finding inside a MySQL client header file?

[aleks-f]

yes, you are right, I did not look past error C2371: 'MYSQL. I have never seen that problem and our CI builds mysql. if you can find a solution that will fix it send a pull and we'll merge it

Just confirming this issue over here:

poco-1.9.0-all\data\mysql\include\poco\data\mysql\mysqlexception.h(26): error C2371: 'MYSQL': redefinition; different basic types 2>c:\program files\mysql\mysql server 8.0\include\mysql.h(293): note: see declaration of 'MYSQL'

Edit: I tested this with an older version of mysql and got the same error: 1>c:\program files\mysql\include\mysql\client_plugin.h(108): error C2371: 'MYSQL': redefinition; different basic types
