[MSEide-MSEgui-talk] create component at runtime
Hi Martin i tried to create a slider at runtime with this code , but nothing appears procedure tmainfo.onbuttonclick(const sender: TObject); var sd : tslider; begin sd := tslider.create(tscrollbox1); sd.top := 10; sd.left := 10; sd.width := 100; sd.height := 25; end; -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ mseide-msegui-talk mailing list mseide-msegui-talk@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mseide-msegui-talk

I don't know why in Linux "/lib" is in librarysearchpath, I also did not find the responsible code. One wold need to debug FPC.

Probably not for absolute paths.

Re-hello. > Maybe librarysearchpath has an entry for /lib where on your system a 64 > bit crtn.o is located? Re-about this, even if librarysearchpath has an entry for /lib (that I did not found), normally, like for all other libraries, it seems to me that there is a check if the file has the correct ELF 32 bit signature. And if the signature is 64 bit, it should look for a other path into the search-path list. But maybe I miss something.

Maybe librarysearchpath has an entry for /lib where on your system a 64 bit
crtn.o is located?

I don't think it is a workaround. -Xd is necessary if in the default library
paths object files with the correct name but wrong arch are available.

Hello Martin.
> Because in linker script are absolute paths, see my mail from 2018-07-23:
Huh, OK, I did read it but the code for the linker script is in t_linux.pas
line 508 (see my post of Jul 24, 2018; 2:41pm)
StartSection('INPUT(');
if linklibc and (libctype<>uclibc) then
begin
{ crti.o must come first }
if librarysearchpath.FindFile('crti.o',false,s) then // NOT GOOD
AddFileName(s)
else
Message1(exec_w_init_file_not_found,'crti.o');
{ then the crtbegin* }
if cs_create_pic in current_settings.moduleswitches then
begin
if librarysearchpath.FindFile('crtbeginS.o',false,s) then //
HERE GOOD
AddFileName(s)
else
Message1(exec_w_init_file_not_found,'crtbeginS.o');
end
else
...
You may see that the absolute path is the same for all files, why only
'crti.o' and 'crtn.o' get the wrong path ?
> I assume the reason must be searched in FPC code.
Yes at first look it is what I think but, after searching in FPC code, it is
not so clear that FPC is the guilty.
IMHO there is problem with the os that does not recognize the good 32 bit
ELF for those 2 files.
But, OK, thanks for your light (and better to forget that bug
fixed-by-Xd-workaround).
