Re: [Lazarus] Do I need separate package files for multiple Lazarus versions?

> Do I need separate sources for each Lazarus version

Under Windows, I have never had any problems using the same package source
for multiple IDEs.  Mind you, my two Lazarus's are target different CPUs
(win32 and win64) as well as different builds and I have this target name
in various compile folders
  IDE - Project Options - Paths - Unit Output Directory =
"...${TargetCPU}..."
  Each Package - Package Options - Paths - Unit Output Directory = "...
${TargetCPU}..."

(where ... just represents the other stuff I have in those folder names)

[Lazarus] Do I need separate package files for multiple Lazarus versions?

[Bo Berglund]

I have several instances of Lazaurs now on my system (1.6RC1, 1.6RC2
and 1.6 release).
On 1.6RC2 I installed a few external packages like Indy10 etc.

Now in order to work on the project in release 1.6 I need to install
these also into that latest Lazarus version.

Do I need separate sources for each Lazarus version or can I just
install the packages from the same source location?
I am using separate Lazarus configuration directories for each
version. And it is all in Raspbian Jessie.

Finally: All runs on FPC 3.0.0 release.

Thanks a lot. I wasn't aware that I must prepend *lib* to the library 
name. Just renaming my link to something.so into libsomething.so did the 
trick!

You should not put .o files into library directories. You should use
the ar command to build a library and put the resulting .a file into
you library directory.

E.g.,

ar -crs libsomething.a something.o

Then put libsomething.a into /usr/local/lib; then use ldconfig (or
SuSEconfig if you're using SuSE linux) to refresh the ld cache.

This is documented in man 1 ar.

I'm aware of that, and I did it, but no luck:-(

Předmět: [Lazarus] /usr/bin/ld: cannot find -lwhatever


Hi,

The result is always the same: cannot find -lwhatever, with "whatever" 
reflecting exactly my external library path/name.


I'm at loss. What I'm missing?

[Lazarus] /usr/bin/ld: cannot find -lwhatever

[Giuliano Colla]

Hi,

I'm need to link some C modules to a Lazarus app.

I started with just a minimal console app, and one module, I've created 
with h2pas the binding module, and edited to make it compile properly, 
but when it comes to link I get the "cannot find" error.


I tried both a mymodule.o object and a mymodule.so shared object.

I tried putting the .o/.so in the source directory, in the unit 
directory, and in /usr/lib64 directory (with an ldconfig to update ld 
cache).


I tried declaring the external library just with the module name, and 
with the full path.


I tried adding the path where the .o/.so file is located in the -Fl path 
of the Compiler Options.


The result is always the same: cannot find -lwhatever, with "whatever" 
reflecting exactly my external library path/name.


I'm at loss. What I'm missing?

Giuliano

somebody shows a way to run a PHP script when the mail server (postfix in
this case) receives a mail.

Cant the same be done with a FPC console application ?


Yes.

The article describes exactly what I meant in my first reply.

Michael.
