https://bugzilla.novell.com/show_bug.cgi?id=649994#c0 Summary: PrinterSettings.InstalledPrinters throws an exception Classification: Mono Product: Mono: Class Libraries Version: 1.2.0 Platform: Macintosh OS/Version: Mac OS X 10.5 Status: NEW Severity: Major Priority: P5 - None Component: Sys.Drawing. AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=397641) --> (http://bugzilla.novell.com/attachment.cgi?id=397641) A project reproducing the issue. User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; bg; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 Trying to use PrinterSettings.InstalledPrinters generates an error: "libcups not found. To have printing support, you need cups installed" on Mac OS X Leopard. This is incorrect because libcups (/usr/lib/libcups.dylib) is present; it is instlled by default because Mac OS X uses it itself for its native printing. Reproducible: Always Steps to Reproduce: 1. Call PrinterSettings.InstalledPrinters in Mac OS X Leopard. Actual Results: An exception that the unmanaged library of libcups cannot be found. Expected Results: Obtain a list of the names of all installed printers (or an empty list if there are none). I made an experiment which you can find in the attached project. I copied the class of PrintingServicesUnix, which PrinterSettings uses internally, from the mono code base, along with its depencencies. After commenting out the usage of some internal members (to be able to compile) I tried to access PrintingServicesUnix.InstalledPrinters. The result was the same, libcups not found. Then I replaced all occurences of DllImport("libcups") with DllImport("libcups.dylib"). Recompiled, ran it again - this time it worked right away and correcty got the name of my (virtual) printer. This is quite strange, I thought the Mono runtime was able to find the libraries on its own if they are specified with no extension as they are in this case? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
