Did you build openssl from source or did you install a software package that was provided by your Linux distributor? In the latter case, which Linux distribution are you using?

jeffreyscottgraham · 2019-10-14T17:41:14Z

From source

bvanassche · 2019-10-17T02:36:24Z

I will have a look but it could take a few days before I have the time to take a look.

bvanassche · 2019-10-23T21:23:28Z

Did you perhaps use the official v5.8 release? Please retest with the latest version of the v5.8 branch (https://github.com/net-snmp/net-snmp/tree/V5-8-patches). This issue has been solved a while ago.

Hi bvanassche,

I had this issue too, I downloaded netsnmp5.8 from here: https://github.com/net-snmp/net-snmp/tree/V5-8-patches and compiled it with openssl-1.1.1d.

However, I met some errors when I "make":

snmp_openssl.c: In function 'DH_get0_pqg':
snmp_openssl.c:31:15: error: dereferencing pointer to incomplete type
*p = dh->p;

Could you please have a look at it?

Many thanks!

bvanassche · 2019-12-15T23:14:39Z

@hanhanlee, please double check which version was downloaded. It seems like version v5.8 was downloaded instead of the latest version of the V5-8-patches branch. One way to download the latest version of that branch is by following this link: https://codeload.github.com/net-snmp/net-snmp/zip/V5-8-patches.

hanhanlee · 2019-12-17T08:55:22Z

@bvanassche , After re-downloading source code from your link, it works fine!
Thanks a lot!!

phuong-dut-es · 2020-02-27T04:02:42Z

still having the same error when download bvannassche patch

bvanassche · 2020-03-15T05:03:28Z

@phuong-dut-es, please provide more information. Which version of openssl are you using and which error message is displayed?

jeffreyscottgraham · 2020-03-29T04:11:30Z

@bvanassche just fix it already. we cant all be dummies

I had the same problem while building static net-snmp 5.9.1 with static openssl 1.1.1l (built manually from source). Configuration script incorrectly detects functions like DH_get0_pqg because of missing dependencies, -lpthread and -ldl in my case.

I bypassed this error by editing the configure script. There are lines LIBS="$LIBCRYPTO" and LIBS="-lssl". I changed them into LIBS="$LIBCRYPTO $LIBS" and LIBS="-lssl $LIBS". And before running the script I set an environment variable LIBS='-pthread -ldl'.

Which libraries must be linked in addition to the ssl library depends on the configuration of OpenSSL and on the platform. Hence use pkg-config to detect these libraries if pkg-config is available. See also "compile fails with net-snmp-5.8 and openssl-1.1.1d" (#25).

bvanassche · 2021-12-28T00:22:59Z

Please install pkg-config if it has not yet been installed and retest with the latest version of the v5.9 branch or the master branch. See also commit 8c3a094.

nonedark2008 · 2022-03-11T10:31:20Z

@bvanassche, thank you for the fix. Just tested with the latest v5.9 branch and everything works like a charm!

jinchaox7260 · 2023-05-09T03:35:23Z

@bvanassche

I encountered the same issue when cross compiling Net snmp 5.9.3 on the Windows platform and adding the header file generated by openssl 3.1.0, but it was not a problem when compiling on Ubuntu. Ubuntu has already installed libssl dev, and I'm not sure if it's related to this?

bvanassche · 2023-05-09T14:36:14Z

@jinchaox7260 Did I understand correctly that you are running a cross-compiler on Windows? I haven't tried this before.

jinchaox7260 · 2023-05-16T08:43:53Z

@bvanassche
Thank you feed back!
After adding ssl and crypto dynamic libraries, the problem was resolved
