Problem with bgrabitmap-9.9.4

[xinyiman]

Hi guys, on a new ubuntu 19.04 machine I want to install lazarus and some of its packages. I found it difficult with the installation of bgrabitmap not even successful with the online package manager. Then I downloaded the latest version by hand (bgrabitmap-9.9.4) but still have problems with the installation. Do you know why?

Code: [Select]

Messaggi, avvertimenti: 75, suggerimenti: 208
Warning: linker: /usr/bin/ld: cannot find -lGL
lazarus.pp(167,1) Error: Error while linking
make[2]: *** [Makefile:4354: lazarus] Error 1
make[1]: *** [Makefile:4784: idepkg] Error 2
Error: make: *** [Makefile:3277: idepkg] Error 2

With an older version the bgrabitmap9.1 gave me a different problem:

bgratext.pas(345,30) Error: Identifier not found "lpNoGUI"

No idea?

Do you have libGL.so ? in lib dir ?

Do you have libGL.so ? in lib dir ?

I run this command: sudo apt-get install libgl1

but error persist

Can you show output of

Code: Pascal  [Select][+][-]

1. find /usr -name libGL.so*

?
or try install libgl-dev

OpenGL is not really necessary for BGRABitmap. If that's the problem, you could remove BGRAOpenGL... units from the package.

Also about lpNoGUI identifier, it is has existed for some time now.

What is the actual version of your Lazarus?

Hmm that may be a problem with trunk.

I had the same problem when trying to install LazOpenGLcontext.

I found the following help:
https://wiki.lazarus.freepascal.org/Lazarus_Faq#I_receive_an_error_during_the_linking_that_states_.2Fusr.2Fbin.2Fld:_cannot_find_-l.3Csome_lib.3E

So I did

Code: Bash  [Select][+][-]

1. sudo apt-get install apt-file
2. apt-file search libGL.so

It turns out the library libGL.so.1 but not libGL.so.
The library libglvnd-dev (Vendor neutral GL dispatch library -- development files) does.

Code: [Select]

libgl1: /usr/lib/x86_64-linux-gnu/libGL.so.1
libgl1: /usr/lib/x86_64-linux-gnu/libGL.so.1.0.0
libglvnd-dev: /usr/lib/x86_64-linux-gnu/libGL.so
So finally I did:

Code: Bash  [Select][+][-]

1. sudo apt-get install libglvnd-dev

And I could compile Lazarus.
