Linux Add-in 1.3.0 Released

I tried the 1.3.0 and it was not possible to compile the buildroot part.

Error acured at  output/host/usr/bin/automake

Hi vienna741,

May i ask what's your Ubuntu version?

If it is Ubuntu 18.04, we will meet error with automake package, please refer to this page: https://ez.analog.com/dsp/software-and-development-tools/linux-for-adsp-sc5xx-processors/w/documents/14051/how-to-build-linux-addin-1-3-0-on-ubuntu-18-04 .

If it is not Ubuntu 18.04, could you please make sure what's your Linux PC version? And what's your target board? ADSP-SC589-EZKIT?

Thanks,

Best regards,

HuanFeng

Thank you for fast reply - I am running  Ubuntu 18.04 at a board similar to sc589-ezkit with DP83867 PHY.

I try this patch and give response immediately after main run is completed.

next stop at make was there:

/home/peter/pmg/buildroot/output/host/usr/bin/arm-linux-gnueabi-gcc -pthread -o pound pound.o http.o config.o svc.o -lssl -lcrypto -lresolv -ldl -lz -lm

svc.o: In function `get_dh512':

svc.c:(.text+0x1edc): undefined reference to `DH_set0_pqg'

svc.o: In function `get_dh2048':

svc.c:(.text+0x1f70): undefined reference to `DH_set0_pqg'

collect2: Fehler: ld gab 1 als Ende-Status zurück

Makefile:43: recipe for target 'pound' failed

make[1]: *** [pound] Error 1

make[1]: Verzeichnis „/home/peter/pmg/buildroot/output/build/pound-2.7“ wird verlassen

package/pkg-generic.mk:184: recipe for target '/home/peter/pmg/buildroot/output/build/pound-2.7/.stamp_built' failed

make: *** [/home/peter/pmg/buildroot/output/build/pound-2.7/.stamp_built] Error 2

the function 'DH_set0_pqg' was at no file inside of buildroot

investigations guided me to changes from openssl1.0.2  --> openssl1.1.0 

I could resolve the problem by editing downloaded files during first run, but I think this is not the way for future.

Thanks for your reply, Yes you are right. Actually we are updating the Linux kernel/uboot in our Linux-addin 1.4.0 release, so we would solve this issue in the next release.

So you edit the download version from 1.0.2 to 1.1.0 in buildroot/package/openssl/openssl.mk and then the error disappears? Since we didn't meet this error when we build the linux addin in Ubuntu 18.04.

Thanks,

HuanFeng

After error stop I added the missing function to dh512.h and dh.h  from wiki.openssl.org / openSSL1.1.0 changes

I know, that this is not the best way, but my app doesn't need an openssl application and any way, which helps to got forward shoukd be used

from wiki.openssl.org:

int DH_set0_pqg(DH *dh, BIGNUM *p, BIGNUM *q, BIGNUM *g)
 {
    /* If the fields p and g in d are NULL, the corresponding input
     * parameters MUST be non-NULL.  q may remain NULL.
     */
    if ((dh->p == NULL && p == NULL)
        || (dh->g == NULL && g == NULL))
        return 0;

    if (p != NULL) {
        BN_free(dh->p);
        dh->p = p;
    }
    if (q != NULL) {
        BN_free(dh->q);
        dh->q = q;
    }
    if (g != NULL) {
        BN_free(dh->g);
        dh->g = g;
    }

    if (q != NULL) {
        dh->length = BN_num_bits(q);
    }

    return 1;
 }

I didn't edit the openssl.mk file. I tried today without success .

I satisfied only the C-language error check.

A fix for this error is present as patch 0001-fix-openssl-1.0.2.patch on the buildroot repo under package/pound/
