Crosscompiling Dillo2 for uClinux on Blackfin

by heisermi＠hs-albsig.de

Hi guys, Currently I'm searching for a small footprint webbrowser to use on my blackin device. This device is driven by uClinux. The first positive I can tell you is, that I compiled fltk2 for blackfin with success. I followed the instructions on tw.myblog.yahoo.com/stevegigijoe/article<http://tw.myblog.yahoo.com/stevegigijoe/article?mid=138&prev=-1&next=137> to compile and run fltk2. My modifications can be read at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?_forum_action=F… So now I'm facing a problem with the configure script of dillo. I had to make few changes to configure.in to recognize crosscompiled Fltk2 lib. These changes went ok but when configure checks libz, then it crashes because it can't find right version of the library. So my question is, how can I tell configure to search in my uClinux directory where the library already is persistent for use with uClinux. Best Regards from Germany, Michae

I don't know whether it's a problem, but I just noticed a difference in behaviour in that my form testcase that submits to localhost (there's no server listening) only prints "submitting multipart/form-data!" and I have to press stop to get '** WARNING **: IO_write, closing with pending data not sent' and see the query.

I added a new function call to the CCC API (wrapping the trick of the previous patch) and used it in three parts of the code. Please check the tip. > If I'm not connected and I try to go to a host that > I have listed in /etc/hosts, then ^Q gives me a segfault. Another SEGFAULT path was: load dillo home disconnect Internet click 9years press stop All of these should be working now. Please report any further problem you find. I'll try to make the empty cache entries removal now, and then look for a way to hook the concurrent connection limit without memory leaks. -- Cheers Jorge.-

If I'm not connected and I try to go to a host that I have listed in /etc/hosts, then ^Q gives me a segfault.

Please try the current tip. It's not definitive, but it looks like with some API polish it may be. -- Cheers Jorge.-

Good! This will hopefully help me clean some old ad-hoc bindings. A simple way to avoid the segfault is to comment the line at http.c:497 (i.e. leave it as it was). Now, my idea is to standardize OpAbort, and have a uniform way to call it and thus avoid ad-hoc calls/non-calls that nobody understands. This may take some time or just a bit (we'll see..). The plan is to include the empty-cache-entry removal feature and improve OpStop once things are uniform. Stay tuned... -- Cheers Jorge.-

If I type "dillo http://laskflsjsdfsf" and then ^Q after it fails to resolve, I get a segfault. (interestingly, if I start dillo with no args [my start url is about:blank] and then try to go to http://laskflsjsdfsf , ^Q just gets me ** WARNING **: CCC: call on already finished chain.)

I don't have a handheld and seldom use one. Despite my efforts, my attempts to try to give good advice on it in the past have proved clumsy and of no much use, so I prefer to follow the advice from the ones using them all the time (e.g. Andreas Kemnade). -- Cheers Jorge.-

I never was able to talk Jorge into this one, but I might as well make the code available so that people with handhelds can have it if they wish.
