Error: Status 1 encountered during processing.

The above error results from the presence of libwww. A pre-build hook should present an error indicating the user should deactivate the libwww port prior to building and installing doxygen. It's fine to activate libwww after building and installing the doxygen port.

[cssdev]

Which platform and MacOS X version are you using? Is your entire port tree up to date?

[brett@…]

10.5.6/intel, all ports current.

The problem seems limited to the MD5 bits.

[cssdev]

Hrm ... it builds and links fine for me on 10.5.6/Intel with all ports current. Could you please:

port clean doxygen
port build -v doxygen > doxygen_build.txt

Please attach that file to the ticket. I'm curious if something else is getting picked up from your environment that makes doxygen build differently on your system. Maybe there was an earlier build error within libmd5?

[brett@…]

I tested on another 10.5.6/intel box (with no other ports installed) and had no issues; from the error above, I'd guess it's picking up libmd5 from libwww's md5 library as opposed to the one embedded within doxygen which has a different API, and that a link reordering should fix things.

[brett@…]

And confirmed: deactivating libwww lets doxygen install cleanly.

[cssdev]

Thanks for the confirmation ... I'm not sure where the best place would be to note the incompatibility. Maybe a preconfigure hook could check whether libwww is installed, and it could present the user with a message that it should be deactivated before building and installing doxygen.

Milestone Port Bugs deleted

[ryandesign (Ryan Carsten Schmidt)]

The easiest way to handle this for now would be to add the line

conflicts libwww

to the doxygen port.

[cssdev]

Replying to ryandesign@…:

conflicts libwww

That seems like it would be prohibitive, as it would prevent having the two ports coexist at all, right?

Is there an easy way from a Portfile to check that a particular port is already installed? (Or would I need to check whether a file from libwww exists in the prefix?)

[tenomoto (Takeshi Enomoto)]

A patch at #22426 will solve the problem without deactivating libwww or making libwww and doxygen conflicting ports.

Applied to r62746, which also updates to 1.6.2!
