BTW,
Are there any flags I should be setting when compiling the .a library into
my .exe to set the ARM acceleration ?
This is the makefile output:
*aarch64-poky-linux-g++ -mcpu=cortex-a53 -march=armv8-a+crc+crypto
-fstack-protector-strong -O2 -D_FORTIFY_SOURCE=2 -Wformat
-Wformat-security -Werror=format-security
--sysroot=/opt/fsl-imx-xwayland/5.10-hardknott/sysroots/cortexa53-crypto-poky-linux
-o cryptest.exe -O2 -pipe -g -feliminate-unused-debug-types
-DCRYPTOPP_ARM_ACLE_AVAILABLE=0 -DCRYPTOPP_DISABLE_ASM -fPIC -pthread -pipe
adhoc.o test.o bench1.o bench2.o bench3.o datatest.o dlltest.o fipsalgt.o
validat0.o validat1.o validat2.o validat3.o validat4.o validat5.o
validat6.o validat7.o validat8.o validat9.o validat10.o regtest1.o
regtest2.o regtest3.o regtest4.o ./libcryptopp.a -Wl,-O1
-Wl,--hash-style=gnu -Wl,--as-needed -Wl,-z,relro,-z,now *
should I be setting for example:
* -mcpu=cortex-a53 -march=armv8-a+crc+crypto*
I use the following for compiling the files:
"-g",
"-c",
"-pthread",
//Add this ???
"-mcpu=cortex-a53",
"-march=armv8-a+crc+crypto"
//
Right now I use the following for building the executable:
"-g",
"-pthread",
//Add this ???
"-mcpu=cortex-a53",
"-march=armv8-a+crc+crypto"
//
"-L${workspaceFolder}/external-libs/lib/",
"-l:libcryptopp.a"
