c++ - How do I compile RHEL5 compatible shared library from RHEL6 machine with GCC 4.4.6? -

-

note: i'am c# windows developer entering c++/linux world.

i have boost based cross platform c++ code need compile shared library for:

  • windows
  • rhel6
  • rhel5 and
  • solaris

i have windows , rhel6 machines , have built those. solaris build not important.

according this: can use shared library compiled on ubuntu on redhat linux machine?

my rhel6 compiled shared library won't run on rhel5, because following command:

readelf -s /path/to/your/library.so | egrep 'glibc_2.([6-9]|10)'

returns glibc2.7 dependency:

143: 00000000 0 func global default und eventfd@glibc_2.7 (14)
9069: 00000000 0 func global default und eventfd@@glibc_2.7

i wondering if there way build rhel5 through rhel6 machine? or other proposal do. thanks.

you can link shared library -wl,-rpath,'$origin' , provide required libraries in same directory.

however, if there in library headers use types c++ standard library, asking troubles. users of library have build , link applications using same c++ compiler , standard library.

the portable option provide shared library c api along c++ header-only wrappers, users can build using c++ compiler.

any ideas when firefox implement lengthadjust andtextlength?..... working svg application. lengthadjust , textlength working fine in chrome not working in fire fox . <svg viewbox = "0 0 500 300" version = "1.1"> <defs> <path id="s3" d="m 10,90 q 100,15 200,70" /> </defs> <g> <text font-size = "20"> <textpath xlink:href="#s3" textlength="205"> short text</textpath> </text> <use xlink:href="#s3" fill="none" stroke="black" stroke-width="1"/> </g> </svg> this implemented in firefox text elements (not textpath or tspan) in case that's ok though can move attribute text element. <svg viewbox = "0 0 500 300" version = "1.1"> <defs>

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11
