#60 Missing configuration file after install

[Jedzia]

Install-CMD:
instcbm.exe xa1541

On a Windows XP SP3 System with a fresh install of openCBM i got "plugin not found" errors. The reason for this was a missing C:\windows\system32\opencbm.conf configuration file.
Creating a zero byte opencbm.conf and repeating the install-cmd above fixes the problem and creates a working configuration file.

Thanks for your report, I can completely confirm it.

The problem was introduced in a patch from October 2012 (commit 8e58fe34849d9)! I will work on a solution and fix it.

For the time being, generating an empty opencbm.conf at the location you give is the correct work-around.

I am sorry for the inconvenience.

No Problem, in the meantime i've done some debugging:

=== 1.) virgin installment ===
C:\Projects\C64\opencbm-code\opencbm\bin\i386>instcbm.exe xa1541
Working directory = 'C:\Projects\C64\opencbm-code\opencbm\bin\i386\',
system directory = 'C:\WINDOWS\system32\',
driver directory = 'C:\WINDOWS\system32\DRIVERS\'.
Copying '.\opencbm.dll' to 'C:\WINDOWS\system32\opencbm.dll'
Copying '.\opencbmvdd.dll' to 'C:\WINDOWS\system32\opencbmvdd.dll'

=== 2.) second run ===

=== 3.) run after providing an empty C:\WINDOWS\system32\opencbm.conf ===

Driver configuration:

opencbm\install\instcbm.c(1474):

Parameter DefaultPluginname = NULL

1. • 2.)
     configurationFilename = configuration_get_default_filename();
     Here configuration_get_default_filename() returns NULL, so control flow leaves the function.

     if (configurationFilename == NULL) {
         break;
     }
     
     configuration_handle = opencbm_configuration_create(configurationFilename);
     
     if (configuration_handle == NULL) {
         break;
     }
     

3.)
configurationFilename = 0x00272490 "C:\WINDOWS/System32/opencbm.conf"
then configuration_handle is set, no error. works.

But if you say, that was introduced by a patch you already know. Well, then I lean back lazily :)
