do i get a performance boost when i compile tesseract as a 64 bit program?

[Simon Eigeldinger]

Hi all,

i am thinking of switching back to cygwin.
msys2/mingw-w64 seems not to give me much luck at the moment.
seems i have issues with leptonica. it can find leptonica but not its
pdf functions it seems.
at the moment i guess i have to decide if i will install cygwin 32 or 64
bit versions.
do i get a performance boost when i compile tesseract with 64 bit?
i also don't know if i can install cygwin 32 and 64 bit on the same
system or if i just need cygwin 64 bit to also compile 32 bit progams.

greetings,
simon

In general cygwin 64 bit is preferred when available.

Tesseract and leptonica are available as cygwin packages.

libtesseract-ocr_3 3.04.01-1
tesseract-ocr 3.04.01-1
tesseract-ocr-eng 3.04-1
tesseract-training-core 3.04-1
tesseract-training-eng 3.04-1
tesseract-training-util 3.04.01-1

Hi Marco,

Thanks for the info.
There is just one question left:

i also don't know if i can install cygwin 32 and 64 bit on the same
system or if i just need cygwin 64 bit to also compile 32 bit progams.

i want to build some out of release builds and haven't found no daily
build server for tesseract so i guess i will build my own builds then
which i will share with people.
i guess i would build 32 and 64 bit versions if i can with one install.

greetings,
simon
